Metro State College in Denver. I taught a 400 level engineering technology elective for a couple of evening semesters in about 1996. Mostly older students working on degrees at night. Lots of fun, no money, looked pretty good on my resume. I didn't like the politics so I didn't want to be any more involved than a part-time instructor at the time. Now I travel too much to do any teaching. I keep thinking about getting a full-time teaching gig when I get tired of traveling and "retire."
