Like Bushbear mentioned about the dry ice, make sure it's wraped in news paper not only will you get burned but your cooler can,t handle it directly in contact, go to costco get there coolers fo 60.00 (igloo) buy 4 block ice at .99 and it will last for 10 day, have two of those coolers and am looking for a reason to buy a nother one just love them Doug
