I was out for a hike yesterday on a trail I’ve been using for years. I’ve never seen another human on that trail before in my life, but yesterday I ran into some people and saw many fresh tracks in the snow. I don’t know why, but it got me feeling pissed off, and after some introspection I considered that I was territorial about the trail.

Is this a normal feeling? Does anyone else feel this? Is it learned or is it instinctual?

Anyways, been in my mind the last couple days, so...
