I've meaning to write about this: a couple of days ago I was riding the Muni underground and there was a man in a wheelchair on board. We ended up getting off on the same stop and as I watched him wheel toward the stairs leading up, I wondered where the elevator was; I'd never noticed it before.

If there was one, it didn't seem to matter to him. He wheeled right over the escalator, got both sets of wheels safely on, and held the moving hand rails to stay balanced. It was impressive, independent, and pretty cool.

However, I have noticed in a few places that the hand rails sometimes move faster or slower than the escalator. Here's hoping he doesn't go to malls, for example, very often...
