I searched but couldn't find an answer. I am driving from Portland, OR to Syringa, ID to meet 9 friends for a 2 day raft trip down the Lochsa . We are meeting around 3pm the day before the trip and I would like to bring a corny with me for all of us to enjoy that afternoon/early evening. It is a 7 hour drive (or so). How could I easily keep my corny cold for the drive over there and the afternoon? I really don't want to buy a Keglove if I don't need to. Thanks for any suggestions!
