Well, I do, right now, because I'm a newbie Jong, and just want to see if I even like it, in a nice, safe, comfy environment with bathrooms and taco trucks. But, even then, I want something to bridge my aerobic exercise conditioning I get from road biking from March to late November. I'm not a racer, I'm actually pretty slow, but I do it to get exercise and stay healthy. I'm tired of getting heavy and slow in the winter, and I don't care if the skinning is in a nice, controlled, safe place, as long as I get the heart rate up for a few hours. But, nice scenery helps. And tacos.
