Hi. My son who is 13 is an intermediate/advanced MTBer and we live in the Santa Cruz Mountains (off Skyline) near Los Gatos. He would love to find other kids his age (boys or girls) to ride with that are the same level. If you're interested let me know and maybe we can do a meet up somewhere in the area. I would call myself intermediate but I've been riding for 7 years in Tahoe and SC mountains. Thanks, Ricardo.
