I had somebody ask me the other day, "Which of the caches you hid is THE one that you would recommend cachers to find?"
I'm not asking for a series. Take a minute, look over your list of hides, pick the one you think is YOUR favorite, and post it here. I offer you the opportunity to crow a bit about your creativity or ingenuity. It can be an active hide or one that was archived and is no longer in the game.
I'll post mine after I see a few listed by others here. Don't be shy. Let's hear about YOUR FAVORITE HIDE!
