Yesterday, I came across some backpackers in a tight desert canyon in Arizona. They were cutting down one of the areas six trees. As I passed, I simply asked "What's up here?" "Firewood." I believe that they knew they were in the wrong, as their answer suggested defensiveness. "It was already dead." It wasn't, I pointed out that the trees don't have leaves because it's winter. "Someone had already started to cut it." I moved on, disappointed by other's behavior.
Cutting down rare trees for firewood in the desert is bad behavior.
What's some of the bad behaviors that you've seen outdoors?
