The further north you travel, the more arid your surroundings get. What used to be forests of brush and trees become more and more sparse. With less to save you from the sun, you find yourselves tiring more quickly than usual. You've yet to come across another resource for water, and your canteens are beginning to run low in this heat. With a day or so between checkpoints, you need to figure out how to replenish your resources soon or you just ain't gonna make it.
