When I was in high school I read a book about PVC pipe being used to cache supplies as well. The author stored everything from a break-open single shot .22 and several boxes of cartridges to camping supplies, etc., and had several buried all over. There was a caveat, he said, with doing this - anyone with a metal detector and a little bit of curiosity could find your stash in the woods before you dug it up to use it, and he wrote this had happened to him several times. I totally forgot who the author and what the title was though. I was surprised enough that the book was in my high school library. I should have swiped it when I had the chance...

Love the PVC chairs as well - looks like something my college buddies would do in their dorm.

THANKS very much for sharing Chisel!
