A wheeled cooler with a drain for groups. I recently bought an IceMule insulated bag that I can throw in the car. With a bag of ice in it, food/drinks are kept cold for a good 24 hours. Great when it's just me away for the weekend.Extended trips away either with the family, a scout group or alone have with them differing pluses, however also come there own issues. One of these is keeping fresh food fresh, and the beers cold.
Everyone has their own ideas on how to achieve this, personally for family trips I have a rather large cool box, which does keep the milk fresh for a few days, however when I either on my own, or with a group of scouts, it stays at home.
I was just wondering what other people did to keep the milk (beer) cold?
