I can attest that Mudskipper's kicked ass last year. You guys were our neighbors 2 doors down (we were Camp Toga), and your floats were delicious and your music was very entertaining!
Thanks guys! Hope you find the right solution. I'd certainly help if I could!
I'm sure you've considered various contingency plans, but maybe you could put it on a trailer in a parking lot and run a genny for a day to get it cold if you can find no better alternative? Perhaps dump a bunch of ice/dry ice into some plastic bins/buckets in the cooler to take the initial chill off (and to prevent any melted/refrozen ice from sticking to the freezer walls).... Kind of a shitty solution, but maybe useful if you get desperate.
