Yeah, you used to find a TON of those War-Amp Tags up here... Found 4 in one day at a ball park not far from the house, but now you can go a long time an not find any at all... When you find them attached to keys, you just dump the whole set of keys into the Mailbox with the tag attached and they make their way back to the owner of the tag and no postage or envelope necessary! Sadly, I doubt that this will last much longer due to the associated costs of returning the keys, etc...
