Plannin on it this year! Hated missin last year, but the elk trip ate up my available free time.
MOJAM is one of the best primitive skills gatherings in this part of the country. Much like the Classic in TN, this is a great place to learn bow building, flint knapping, arrow making, string making, fire starting and much more! There is limited space for primitive camping and campgrounds in the area. Trading is common and encouraged, as well as cash purchases. Concessions are available as well as porta john toilets.
The folks are top notch, family friendly atmosphere, kids always running back and forth, and the volunteer staff are always super helpful. I guarantee, if you take the time to attend you will walk away with a new found faith in humanity and probably a few more skills for your possibles bag.
At least, that's my perspective after making it a priority for 4 of the last 5 years.
