ammo cans > other stuff
I've placed 4 caches: 2 micros, one nano, and one ammo can, and I feel a lot better about the ammo can.
I've also given away about 6 (or 8?) ammo cans to local cachers, pre-camo'ed and ready to go, so I don't feel so horrible about my smaller containers.
Anyway, I'm not really about the swag, but I just dig an ammo can (I'm ex-military).
