I've run into several folks out here in SE KY that make their own. Some good. Some bad. I've been wanting to give it a try for a while. Looking at that kit on Amazon has me itchin even more.
Curious what they do with all the trash/waste on these mountains. Read a piece on Everest and how it's getting crazy polluted. Kind of odd how these places are revered for their challenging terrain but no one bothers to keep em clean.
