My 14-year-old is really getting into riding. The kind that involves goggles, full-face helmets and being in the air. I'm stoked that he likes riding. One of the things we'd like to try is a pump track. We're in the Oakland hills. I know about dirt jumps nearby, some clandestine, which are pretty big and have significant consequences. I'm talking no-pedal, pumptrack. Where's the closest one? Yeah, sure we'd love to build one, that's another matter.
