Here's a picture from what I did yesterday. Henry Cowell Redwoods State Park is about a 10 minute bike ride from my front door. In the photo I'm fording across the San Lorenzo River. From there I rode uphill into Santa Cruz Pogonip Park, onto the U-Conn Trail, and then I did a couple of loops through UCSC forest trails before zooming downhill into the city of Santa Cruz where I caught a bus back home. The weather was beautiful -- sunny and with a high of nearly 80°F in November! Like Jason wrote, "Being a cyclist means hating global warming … but liking it warm. Oh, the humanity!"
The bike is an old low-end GT mountain bike that's now about ten years old but still going strong.
Mountain bike tip of the day: When you hop over a 12 inch log, watch your landing zone for large obstructions! If you don't, you might face plant like I did -- that's dirt from the trail on my face after I shoveled straight in just like Steve Austin's experimental spaceplane shoveled into the runway in the Six Million Dollar Man.
