I am still around. Not riding dirt much these days though. When winter rolls around I usually stop riding my mountain bike, and start focusing more on running and swimming (indoor gym).
Hard to get motivated about riding when it is cold, and if you wait too long in the afternoon, the ground becomes mucky.
Winter off-road riding in NE sucks as far as I am concerned. Haven't had good luck with it, so now I pretty much avoid it altogether and do other things instead.
Once the weather warms up, and the trails become less mucky, I will be back in the saddle. But until that time, it's running and swimming for me.
