Excellent points. Thanks for all the replies. I do have a few pieces that I really like. So I might just hang on to those pieces.
Speaking of hitchhikers, I remember my rocks came with a few crabs. Tiny like 1/2 inch. They weren't hairy. But yesterday as I was pulling rock out I found one of them and it grew to at least 2". Too bad it was dead. But I haven't seen them grow that big before.
