We were in the Arapaho NF in CO and, after the sun went down and a bowl of strong Colorado herb was burned, we all became very paranoid of bears. There were lots of slender long pines that had fallen in this area, so we constructed crude fortresses around our tents. Haha! We even whittled some of the sticks with sharp points at the end to stab any bears trying to murder us in our sleep. lol
