I totally applaud your involvement with BCA. When I was wheelchair bound and had to go to work... I can really experience how its like commuting from my home, to the train and to the place i work. Every movement I have to think in advance. Knowing which exits have lifts and which side of the building have ramps.
So what you are doing is really good for all, cuz as healthy as we are now, some day, we have to depend on walking stick or even a wheelchair.
