>>1224051I started this about a year ago to get me /out/. The Sithsonian has a very good guide book you an get from Amazon for cheap. I'm looking for flint, but in MI we only have chert.
However, rock hounding creates a way of looking. I pay better attention when I walk on the beach or through the woods. Plus, that cool hammer is a babe magnet and can help you escape from prison if need be.
