Thanks for the "confirmation", guys! It sounded feasible to me so that's what I'll do.

I am definitely thinking about planting em under my portable back yard fountain in a flower bed. I think that the distraction of the perdy lil fountain and flowers would be the perfect hiding place. I believe in the "hidden in plain sight" theory. Now, I have to acquire the PVC and get on it ASAP.

sidenote:
A relative of mine said that he recently had a "surrepitious" entry/raid [while not at home] by the cops due to some lady who had falsely accused him (simply accused him mind you) of being a terrorist. He told me that due to his burying of his boyz toyz under a bunch of storage items in a basement type area, they overlooked the toyz and moved on. He discovered/confirmed the "entry" through another neighbor who noticed the activity.

That's what I want. For them to totally miss em if they come lookin.
