Backpackers as a group tend to value quiet, solitude, and nature. They can be sensitive when they encounter other people with less refined sensibilities. This forum has a common thread of instances when backpackers are incensed by what they perceive to be rude or illegal behavior.

There may be lots of rules and permits in place to regulate backcountry areas, but the reality is that enforcement is very difficult. Wild areas by their very nature attract people who do not care about rules.

My brother has travelled the world on the road to find out. He has been teaching me, not to give rude people the power to upset me. Just ignore them and live in the world as it is. People do not deliberately try to ruin your outing, they just have a different frame of reference.
