Well, my brother in law said the only two he would go to are Boulder Outdoor Survival School in Boulder, Utah, and Wilderness Awareness School in Duvall, Wshington.

One thing he didn't mention is a primitive skills conference put on by Backtracks. I know he and my sister have both been to Rabbitstick (put on by Backtracks). You can check them out here:

I don't know if a conference with classes to sign up for is what you're looking for, but it's an option.
