I haven't rode a mountain bike is so long. I used to live in Aliso Viejo, Ca and backed up to Aliso Wood Canyon. There were all kinds of single track, up hill and down hill. Loved it. I used to ride 4 or 5 times a week. Not so much since we moved to Vegas. I have a GT carbon with all kinds of after market parts. (Chris King head set, XT and XTR componets, Marzocchi Z1 Bomber shocks, etc.) It would be nice to maybe go for a few rides while the weather is still nice.
