I'd really like to take the advanced bushcraft class in March 2018. Do these classes fill quickly? I guess what I'm asking is if I should reserve now in order to get in. Are there any special requirements I should know of or be prepared for? I don't want to hold everyone else back. Should I be able to hike a certain number of miles? I didn't see a PT test requirement on this class, but is there anything I should be aware of? I've got a lot of questions about several things, please be patient with me. I'm trying to find a former self, so to speak, and I'm years out of the loop.
