Actually wandering around the campus was the clincher, though. The crowd seemed very young (like, up to twelve years younger, imagine that) and... kinda dumb. When I looked into some of the classrooms, they looked like they could have been straight out of high school. The tones the profs were using were (in a bunch of cases) clearly "down to" the students. I've been spoiled by being competent at what I do, and I don't know how well I could take that sort of thing these days. Looks like no (more) college for me for a while.
Looks like I'll have to start using the watercolors (and possibly start writing) after all. :)
