So today I was coming down National just above the Mormon/National upper split and this other dude was riding just a bit faster than me and every corner was skidding the hell out of the trail. Then at the junction proceeded to roost a group of hikers. They were pissed and yelling at him and me. He kept bombing down the trail oblivious. I stopped and explained that I was not with him but that nearly every biker knows to slow down and not shred the trails to ****. They were nice and I told them if I could catch up I’d say something. I was able to catch up and let the rider know a bunch of hikers were pissed at his actions. Dude couldn't have cared less. Complained more that hikers sometimes get in the way or don’t pick up their dogshit. Point is there are a lot of noobs on the trails so if your group has a dickhead that feels it is necessary to blow out every corner please educate them to knock it off. I don’t want the novice riders to think it’s ok to mess up a trail and not take responsibility for doing it.
