Where to go to learn about cars?

[Gary]

Anyone who has read my threads knows I don't know jack about the finer points of mechanics, where is a good place to go to learn at least a good grounding in auto mechanics? Maybe some courses at a local tech college was my idea, is there other ways of learning how these old trucks work?

I'd like to begin rebuilding my old truck but it's pretty obvious that paying mechanics to do all the work and body shops to do all the body work is going to cost a bloody fortune, plus I have always liked cars just never got to learn about them much.
