perhaps you should spend a few days confined to a wheelchair. then perhaps you can understand why there needs to be ramps on sidewalks.
We had an administration that refused to put automatic door openers - like most shopping malls have. We managed to have them spens one work day (7-8 hours) in a wheelchair. Within three weeks we had automatic door openers.
You remind me of the wheelchair-bound doofus who held up the new bus system of an entire town because the buses did not have access to her liking, even after they offered her instant limousine service any time she needed to go anywhere day or night... while they ordered a special bus.
