My father needs help getting around in public. Is there somewhere I can look to get him help for mobility during his travels?

Buz, I see from your profile what medical and mobility issues your Dad has.

My Dad had mobility issues where a cane wasn't much help anymore. He tried a regular walker and didn't like it. Then I bought him a rolling walker [has 4 wheels instead of 2] which had hand brakes, a seat, and basket.... he said it was the best thing since sliced bread, he loved it. He was rolling all over the place :) And when he got tired, he would set the brakes and sit on the seat, which was pretty comfortable.
