The owner of this site has a comercial permit to remove and sell boulders. The Dept. of Fish and Game makes him identify and mark his work areas. He got mad and named some of the rocks after the officers that bugged him. Look at this crack I found yesterday. It's full of square and round nails. I'd better clean that one out. No luck on finding your bird?aa battery said:Do you know what the number 4 means just curious?
