-06 Just had to laugh at that "who wants to steal a picnic cooler..". Around here Picnic Coolers are used for a lot of things. One of those is for BEER in the back of a pickup for a quick refreshment in the Company parking late while on the late shift. A well known imbiber noticed his stash was depleting more than usual without the expected FRNs slipped into the cab through a lowered window. No problem, being dark and all he set up a second Cooler, complete with ice and Rattle Snakes! The Snakes may have been dead or just asleep, no one was talking, but after that night exchange of goods continued at a fair rate. HK
My bid goes for the heavy duty plastic sleeves used for coins. Size varies per coin and they are tough as nails. Can be made water proof with tape or other sealants.
