I'm really trying to talk myself out of, or maybe into a fridge, I dunno.. But I recently picked up a 2lb Nu-ice ice pack thats rated to retain 0° temp for up to 96 hrs. They also make a 32° pack thats rated for the same 96hrs. Haven't had a chance to try it out yet but hope to soon. Most of my trips these days are 3 day weekends so if they work as advertised they should work out perfect. The guy at West Marine said the 0° pack froze a bottle of water in his cooler, I'm gonna try it tonight. Anyone else tried one yet?
