I'm going to be in Tucson for a week of boring engineering seminars and am planning on bringing my camera equipment. I'm wondering if anybody has any suggestions on interesting places to take pictures. The Class runs 0730-1630 so I'm looking for good evening and/or night shots.

Also, I'm driving from San Diego and if there are any interesting locals between here and there, I wouldn't mind the opportunity to get out and stretch my legs.
