I pretty much do the mountain man thing as a lifestyle for the last 30 plus years, and am a professional Indian hobbiest. So I don't need to tan hides or do beadwork for sport. I get plenty of that in day to day work. I'm heavily involved in cast bullets in modern bottleneck rifles, and am involved with a working group writing a book on the subject. Shooting is my main hobby, no matter the firearm type, or style of competition, from combat pistol, military rifle, to BPCR, to muzzleloading. I build a few rifles from time to time, from ML's through Mauser sporting rifles. I do the engraving and checkering work, so these projects can fill a month or so in the winter. I do enjoy fishing, or just going out and wandering around in the mountains for a few days at a stretch. I build and play instruments, fiddles and mandolins mostly, and play bluegrass, old time cowboy and country music generally. I have been known to get into some serious acoustic rock and roll and blues with Dr. Mongo and the boys. I'm building an early fretless banjo at the time. I also do oil paintings, mainly native American subjects.
I used to make moonshine for a hobby, but liked that one a little too well....
