I'm not as horrible a cane-user as I thought. (Roughly, this means that neither I nor anyone else was maimed as I walked to and from class.)
I don't think it took me significantly longer with the cane, which means Glaze really has slowed down.
But, here's the trick: You have to just *move.* This came to me in an epiphany this summer. (It's possible that everybody else already knew this...) If I move hesitantly with the cane, my environment is going to sound different, and I'm going to get lost. If I move quickly, I'm basically following the paths that Glaze uses (I did go farther over to the right today on the walk home, and I found a bench I didn't really know was there; I have to remember that). If I walk slowly, I have to pay more attention to things like the number of doorways I pass, etc. If I walk more quickly, I know what to listen for. (The class supervisor at GDB said I did have a really good sense of "echo location." I don't know if mine is better than average or what, but I do know that speed plays into how I perceive the shape of my environment.)
It's kind of creepy, the way people stop talking when you get close to them with a cane. Actually, I think some people do that when you get close to them with a dog, but boy, it sure is noticeable to me with the cane.
