I have a problem. The problem is that since i have been in college I have developed a taste for expensive beer. With that said, this time of year especially for backpackers when you can put your beer in the river and let it get cold. If you are a Guiness fan like myself, go to the store before your weekend excursion and pick up six of em put them in the top of your pack and enjoy the night with Guiness in hand. The river gets the beer extra cold and makes it perfect for drinking. Makes a cool picture too.
