So just to make sure, you basically just have a big YETI type cooler or a big styro-foam cooler that you kept your BP's in? Placing the BP's in a snake bag and then surrounding them with bottled warm tap water? Sounds like it would work, but what about air though? Do you leave the lid cracked?

Some guys at work also mentioned those portable electric power packs that can run electric items for a while. Theoritically I could hook up the under tank heating pads to that, but I'd still be worried about how long that would last plus the ambient tempteratures at that point.

Unfortunately I'm one of the poors and don't have a house yet... haha. But I'm working on it! I was getting relatively close before housing prices exploded and left me in the dust.
