Winter is coming! Snow is possible here later in the week: not likely at this point, but it's fun to think about.
Since last winter, my MTB became a single speed: no more derailleurs to maintain. I'm also going to try some slightly wider/tour oriented tires on my single speed to see if I can cut down time on the MTB.
I also ponied up for proper rain gear, which will help with slush as well. No excuses this year. I'm ready.
