I go on a week long backpacking/ canoe trip in Algonquin park in Ontario every summer.
Basically, we load all the food and supplies we'll need for an entire week into packs, throw them into canoes, and head into the back country for a week.
I always take a stack of PotSM cards with me - it plays well on a flat patch of dirt by the campfire. Since the cards are plastic I don't worry about getting them wet or dirty.
