I have a feeling that I should have learned this somewhere along the way but I didn’t. Did you know that you can use an analog watch as a compass? In the northern hemisphere just point the hour hand at the sun. Then imagine a line halfway between the hour hand and the 12. It points to the north. I’ve been trying this randomly for the last few days and it works. For a full explanation check out this site. While you are there look at the rest of the site for explanations of how to pack for extended trips using only one bag. Very cool!
