I was out overnight Thursday and back Friday afternnon. I packed two coolers with ice for drinks, brekfast etc.

I just bought a new Igloo cooler for the trip and I has my Coleman cooler as well. Cleaned up the boat this afterneoon and the Coleman cooler had luke warn water and the Igloo cooler had ice in it (4 days +/-).

Look in the gear thread for a used Coleman cooler cheap.
