Good question. I didn't really have much training, myself (New Jersey).
I had AutoCad my junior year in high school. The following year they had a new teacher teaching it- awesome teacher but he never used the program before. I basically taught that course for him.
I went to Brookdale college for 2 years- they have a couple AutoCad classes, but I didn't use it the whole time I was there.
When I went to NJIT, most professors made you use 3dMax or something similar- not much AutoCad, at least in the classes I took. The do have a couple AutoCad classes, though.
I suggest getting your hands on a copy and just fooling around with it. It's really not hard to pick up, at least in my opinion.
