Keeping the beer cold. Making sure I get the beer before I get to the campsite. Buying enough beer so I don't have to go off on a beer run while cooking dinner. Buying the beer 30km away from the campsite because the map doesn't show any facilities nearby. Getting to the campsite to discover there is a supermarket and 3 convenience stores nearby. Starting the day hungover with a climb straight up. Weighing myself at the end of a trip and discovering I haven't lost any weight because I've drunk so much beer.
