How did you practice for procedures?

Have any of you SRNA's or CRNA's had the opportunity in school to practice procedures, like spinals, epidurals, or central lines on cadaver patients? How bout mannaquin patients? I've heard of practicing intubations on mannaquins, but I wondered also about other procedures as well?

I've seen a cadaver maybe once during my schooling so far, and of course didn't have nearly enough time to pick out all the landmarks I wanted to. I think it would be a good way to teach central line insertion at the very least.
