'Ay man, Sylvan Hart lived nearby for decades strictly on what was naturally available, by and large. If that ain't proof that all you need is right there, then I smell with my ears and write with my nose.
CON-GRATS to ya, bud!
BTW If you're not hip to Hart, aka "Buckskin Bill", I'm sure the older locals can prob'ly fill you in a bit. He was a rustic renaissance man.
