When we lived in new mexico i used to hit a trail that was a steep fireroad climb to super long, exposed downhill singletrack. It was a great trail because you could let go of the brakes and just haul ass. As a bonus it was a lot of work to get to and remote so less traffic. HOWEVER, without fail there were hikers doing exactly as described above complete with headphones and paying zero attention to their surroundings. The worst were the moms who actually took their kids out in offroad strollers on this trail. F@cking strollers! Almost ran right into the back of one on a blind corner and had to fly into the desert to avoid her. Sucked.
I'm getting to the point where I just want to ride at bikeparks.
