I live near and ride around most of the entire Stanislaus river watershed, and the forest itself has a fair amount of bike trails. Snow (if we get it - this is likely to be in your favor, really) is usually what keeps us out in November. Lately though, November has just meant cold temperatures with some rain. I take it you're looking for off-road routes? Where are you considering starting, and where would you want to end?
You know, haven't really thought about the starting point. We'll have a car so I was hoping there'd be a trailhead(granted it hasn't been plagued by vandalism) that I could park at and complete a loop back to the car.
I appreciate you getting back to me and any information you could pass on
