there are many levels to disability. now are you saying that i have to have a dr's note every time i use my wheelchair? that a place can tell me i cant bring my wheelchair in because i dont have a dr's note?? I don't have a note. I bought my wheelchair myself. My old dr is aware, my new one is not. can you see someone telling a person who has been in a wheelchair their whole lives that they must prove they need the wheels?? what do i have to do, try to stand and fall?
what about temporary disabilities - when my mom pinched a nerve in her foot, should we have had to go to the ER in orlando, paid $1000s in out-of-network costs, when we knew what was wrong? she needed a wc for one day at disney. that sounds to me like you are punishing people for getting hurt...
i cant afford a lot of drs right now, and i am un-dx'ed, so it is even harder to get a "dr's note" saying what is wrong - we dont know!
do you see where the problems arise?
and your Metro comparison is inappropriate for the situation: yes, people have to prove disabilties for things that the average able-bodied person does not get, like discounted fare. the same goes for SSI/SSID, HC parking, special housing disocunts, etc
however, we should NOT have to prove disability for EQUAL ACCESS, like going to the mall. THAT is what is illegal
