RIO DE JANEIRO -- Inside the Olympic Park, there are ramps, strategically placed railings, tactile paving inside venues, and more. Bobby Orr Jersey . Its evident that experts designed the grounds for the Summer Games and Paralympics to be accessible to people with disabilities.But outside the venues is a different story. For those with disabilities, navigating Rio de Janeiro can range from inconvenient to daunting, something Brett Gravatt can attest to.Gravatt is a student at Penn State who uses a wheelchair and is part of a journalism class visiting Brazil to help supplement coverage of the Paralympics for The Associated Press. Though the students are staying in a business hotel close to the main grounds, the morning commute for Gravatt through a recently developed neighborhood involves navigating his way down a dirt path, through weeds, rocks and tree roots.His classmates walk along a sidewalk that is not smoothly paved, but made of flat stones, each several inches high, with a big space between them.Separate but equal, Gravatt jokes, as he makes way to the rapid transit station, which has a handicapped entrance and space on the bus for a wheelchair.Its just a taste of what life in Rio -- a place with glaring contrasts between haves and have nots -- is like, advocates for the disabled community say. While some improvements have been made to the sprawling city of more than 6 million to improve access for all its citizens in the run up to the Olympics and Paralympics, including a new commuter rail line, even organizers agree the situation is far from perfect.I mean, officially, all of the venues here are accessible and they are more accessible than anywhere else in the city, said Mario Andrada, spokesman for the Rio organizing committee. But if you have an accessibility expert he or she will find a lot of black holes.It doesnt take much to make life harder. On a recent night at the track and field stadium, for example, someone parked an official Rio 2016 car so close to the access ramp that no one in a wheelchair could use it -- instead leaving a curb at least 3 inches high to negotiate.And even in Centro, Rios upscale downtown neighborhood, the mosaic-style sidewalk does not lend itself to anyone in a wheelchair or who has trouble getting over uneven surfaces.On paper, the rights of the disabled are well-established in this nation of more than 200 million people.In Brazil, we have great laws but theyre not enforced said Teresa Costa dAmaral, founder of the Brazilian Institute for the Rights of the Disabled Person, a group that files civil suits to help protect the rights of disabled citizens. Its not the laws that are the problem its our government.The issue is far worse for the citys poor, she said.If you live in a favela you often have to stay home unless you have friends or family to carry you in and out, Costa DAmaral said, a narrative 38-year-old Carmen Lucia Mansur knows well.Mansur was born with a congenital birth defect affecting her legs and limiting her mobility. Mansur has four children, and her 18-year-old son, Yuri, was born with the same birth defect.Both Mansur and Yuri have undergone multiple surgeries, fully covered by the Brazilian government, to improve their condition. Mansurs abilities have improved dramatically, whereas Yuris have not. The young man must rely on crutches to walk.As a result of many medical absences Yuri has been held back in school. At age 18, he began high school this year. He was initially set to attend a local school with his neighborhood friends, but discovered that the school only had stairs and was not accessible.So he had to attend a different high school, Frederico Fellini, because it was equipped with ramps. But that caused another problem: Although the school itself is more accessible, getting there is difficult.Mansur met with the principal to request transportation for her son because of his disability: That was denied. The principal says the school doesnt provide transportation to anyone.Yuri attempted to take the public bus to school on his own, but found that, once he made his way to the distant stop, if he was alone the driver would not stop.I worked for three years, then I had to choose between work and my kid who has a disability and I opt for my kid. Now Im unemployed, and on a daily basis its difficult to get him on a bus, Mansur said.Yuri said the greatest difficulty is when he gets off his bus and begins his journey home. He described making his way up 41 stairs. I go up five or six steps, and then I take a break, and go, he said.Costa dAmaral is skeptical there will be long-lasting change made in the city as a result of the games.I always said it was `errado, wrong, to ask to do the Paralympic Games in a city that does not respect disabled people, she said.But Andrada says the city has come a long way in the past seven years, since the games were awarded to Rio.The capacity of Rio public transportation for wheelchair people was eight (at the time), he said. We had two vans that could carry eight people -- just the Dutch delegation has more than 160 people in a wheelchair.Andrada conceded that we (the city) are behind but says he believes the games will help changing the mindset, but it will take at least a solid generation before Rio can be considered totally accessible.Mansurs son Yuri noted that, at a time when Brazils government is in turmoil, its hard to tell whether the Paralympics will have a lasting impact. But they did in the short term.Ive seen some improvements in the city in terms of ramps, the pavement on the streets. In my neighborhood, Ive seen these improvements, he said. For me, if the games werent here things would have stayed the same.---Shannon Ryan and Brett Gravatt are journalism students at Penn State University.

Jenson Button thinks the rest of the field are letting Formula One down by failing to challenge Mercedes for the third season in a row.Mercedes looks locked in for a third straight constructors crown, while the drivers championship is once again a two-horse race between Lewis Hamilton and Nico Rosberg. The German manufacturer has dominated F1 since the introduction of the V6 turbos - it has won 43 of the 50 races since the start of 2014.Button believes the rest of the field have simply not done a good enough job.When asked about the Hamilton-Rosberg title fight, the McLaren driver replied: Its a not a fight were involved with. Its not a fight that really makes any difference to me whatsoever -- who wins or who doesnt win. For me, the important thing is we get other teams involved fighting at the front, because having just two guys in the same car fighting at the front is not what the sport needs.It needs other manufacturers involved, other teams involved, and thats where were letting the sport down by not doing a good enough job. Races like Barcelona when Mercedes werent in the race [after crashing out], everyone loved it because there were four cars fighting for the win. Johnny Bucyk Bruins Jersey. Thats something we hadnt had for three years, so hopefully well have more of that in the future of Formula One.Regulation changes next year will move the onus back towards aerodynamics, with wider and more aggressive-looking cars. Much has been made of the strength of Mercedes engine but Button thinks it is wrong to assume that is the only reason the world champions are doing so well.In terms of why theyre so good? I dont know. I think if we all knew, wed be as good as them. They have a lot of very talented people, and maybe the [current] regulations are in their favour.For next year, could they be caught out? Maybe. Possibly. But then I dont really think their power unit is that superior compared to the Ferrari, for example. They just have a very good car. Their overall package is fantastic.I dont think you can just point at the engine and say, thats why theyre performing well, because there are lots of other cars with the same engine that arent performing anywhere near as well.
