So I normally knap on the side of my garage on concrete. It is pretty simple clean up. I have been thinking for months on how to make a pit in my yard to keep any stray chunk from ending up in my foot (or worse my wife's). It dawns on me that I have a 10x15 area on the other side of my house that isn't used for anything, is shaded and is all sand. What should I include for my pit? I'm thinking a small "pole barn" type structure to keep me out of the rain and snow. Thanks for the ideas I know you will give me.
