In reply to sutty: Having recently been forced to using a wheel chair myself I can totally agree with what your saying, loads of things that we take for granted in our everyday life become near impossible for the diabled, for example all pavements slope for drainage purposes and to allow cars to cross them to get to there drives, unfortunately when your trying to wheel your chair your constantly fighting that slope to stay in a straight line. B*ggers that park half on the pavement don't help either.
I personally think that all architects, and town planners should be forced to use a wheel chair as part of their training maybe then they would realise just how difficult things are for the disabled and would plan things accordingly.
So when you watch the para olympics later this month marvel at how hard these people have had to work to become the athletes they are.
