A few years back I had read an article or seen something on television - I no longer remember which - that said that they had discovered that many handicap stalls in public bathrooms don't have a door handle on the level needed for the person in a wheelchair.
The next time I went to my public library I checked- bingo! They were mortified when I told them and they said they would take care of it right away. And they did.
The house museum that I lived in and used to operate did not have a code bathroom but there was room, just barely, for a wheelchair. In the 12 years I lived there I had only three people visit in wheelchairs . One was a volunteer docent whom I had recruited, one was a young woman I met downtown and invited up the hill and one was a guy who had been sent to ascertain that it was accessible.
