A tree blew down across one of my favorite little pieces of singletrack this summer, and when nobody cleared it with a chain saw, some freeride types built a ramp stunt over it. On one hand, this pisses me off because I'm not a fan of unnecessary structures on trails. On the other hand, it was fun to watch Pete B. and a couple of other young guys riding over it on their singlespeeds one night last week.
The whole "North Shore" style of riding doesn't appeal to me. I like my trails as natural as possible (although I do enjoy the ramp on Brown Bear) and scrap lumber is an affront to the beauty of natural forms.
I also like staying close to the ground. I can fall hard enough from saddle height, thank you very much.
Several years ago in his Mountain Bike magazine column, Dan Koeppel wrote about some formula he uses for catching air. I don't remember exactly what the formula was, but it somehow involved one's age having an inverse relationship to the number of inches their tires should be above the ground.
It seemed clever at the time. It seems wiser with every passing year.
