For those of you who prefer nubby tires to skinnies, Mammoth Mountain will be right up your alley. I took a little mountain bike vacation a couple of weeks ago and biked above June Lake and then Mammoth Mountain and brought both the Santa Cruz Blur (full suspension) and Ellsworth Enlightenment (hardtail). Didn't need the very light hardtail as most of the climbing wasn't terribly steep. The Santa Cruz Blur handled the easy and moderate trails without a problem. Mammoth Mountain consists of miles and miles of dirt trails up, down, and across the mountain with varying degrees of required skill levels. The trails are very well maintained and well designed, and worth more than the $10 day use. If you choose, you can take the Gondola up to the top, and bike your way down, which costs about $40. The trails are all rated like a ski slope, green circle, blue square, black diamond, and double black diamonds. Next year, I plan to stake out some prime photography locations as there are many tricks to perform off the black diamond and double black diamond trails. You won't see me on them, but I can get some shots of teenagers flying through the air off ramps, tree trunks, over tunnels, etc. So, instead of seeing me fly through the air, I have a couple of me just trying to navigate some lines through rocks near the edge. I know, nothing technical or tricky, but beautiful scenery nonetheless. Enjoy!
