I for one love nanos, but if only I have to hunt for them. The magnetic keyholder or film canister placed on the sign or in the guard rail is booring. Sure, it's a quick P&G but I'm in this sport about fun, not racking up chaches I've found. It doesn't bother me in the least if I have to go back a couple of times. Sure it's nice to find an ammo can full of swag, especialy if the G-Kids are with me, but no-one leaves anything worth trading anymore. I used to leave lotto tickets in every cache I found but due to people not reporting if they had a winner (not saying they had to) I kind of stopped that practice. To get back to the topic, my favorite caches have either been nanos or nanos in the stages of a multi.
