In college I had a mountain bike. I rode it all over San Francisco for transportation. On the weekends, sometimes I pretended to be a mountain biker and went to trails in Marin where I would walk most of the 'ride'. Then, a back injury took me almost completely off the bike for a few years. That's when I loved surfing and hiking.
Then, I discovered triathlon and road cycling. And, it's been a 6 or 7 year love affair with the road. All road all the time. My favorite non-training-specific activity is discovering a new gem of a road that I've never ridden before - or some new combination of familiar roads. But, the prospect of venturing on to the dirt on a road bike, or even touring bike freaked me out.
This year I went on a few mountain bike rides and did a CX clinic and race in the name of improving my handling skills. Now, I'm all confident and stuff. I know I can ride a fair bit of dirt on the road bike, and can ride just about anything I want on knobbies (not counting boulders, logs, and massive drop-offs).
Now, I find myself daydreaming about quiet roads that end in a bit of dirt or single track and connect up to other interesting roads. I practice my mounts here and there. The possibilites are expanding. I like singletrack. I never thought I would say that. Heaven help me, I think I'm becoming a dirty girl.
