Nature's Own president Roy Young likes digging in the dirt. When he isn't manning one of the store's five Colorado locations or promoting environmental awareness, he travels the world in search of fossils; many of those specimens wind up on Nature's Own's shelves alongside rare minerals, handcrafted onyx, educational materials and lots of fun prehistoric products. The stores are a tree-hugger's dream, helmed by an earthy guy who puts his green behind his green beliefs: In November of last year, Young donated a month's net income from his stores to state environmental groups.
