My brother and I are XC/trail riders in our mid 20's that live in Modesto. Since the biggest "mountain" within riding distance is a highway overpass, we usually like to try to take trips to explore new trails in some real mountains at least once a month. We typically ride anywhere in the Bay area or the Central Sierras and are always looking for new trails.
Some of our favorite rides from this summer were Mt. Diablo, Bass Lake(South Yosemite), and all of the trails in UCSC's upper campus/pogonip/wilder ranch.
Is there anyone within a 2 hour drive that might want to ride with us, carpool, or just show us your favorite trails?
