Shop Class For Grownups

When I was in junior high and high school, I had a totally academic program, so I never took any shop classes. If I could go back in time and have 27 hours a day instead of 24, I'd take shop classes too. In the meantime, I've added shop to my remedial education list.

So, where do grownups sign up for shop classes? Any kind of shop (metal shop, plastic shop, etc.) will do, since I know nothing about any of them.
