|Wanda, it sounds as though Access is far better than anything in the UK. We have to put up with public transport or drive ourselves. Locally we have a neighbourhood association which gives people lifts to hospital appointments etc. I don't know if this is so in other places. I have only considered myself to be disabled for a couple of years.
I hear what you're saying about the homeless we have a problem with this in the UK but it is worst in London.
I am sorry for your pain and can only say that I'm here for you and send a big hug across the miles. Sorry must dash. Quaver
