Any store that sells LPS products should be able to order the #3 for you. I bought mine thru a tool store. PVC pipe can be picked up from a local handiman/DIY store. 12" pipe will need to come from a plumbing wholesaler.

There are several books and videos out there about caching and secret hiding places. Most of them are pretty good.

SIDE NOTE ON PVC. Several years ago, just after the first ban went into effect, I went to the local lumberyard to buy some PVC. The largest I could find on the shelf was 4". I asked the young girl working in the department about the 6" and why the shelves were empty. She was only about 17-19. She came right out and told me "You will have to use 4" and take the stocks off!"

If you cache in your own yard,make your cach harder to find by burying several empty metal paint cans and beer cans in your yard. This sounds like a beginning of a good article! I'm starting to write it now.
