Hey, I never followed up on my 60-degrees-and-raining commute post.
Conclusion: Long sleeve jersey (thin merino wool), rain jacket, and baggy shorts are fine, bordering on too warm.
The next day was a 50 degree ride through dense fog. I had forgotten one little aspect of fog: It makes you wet. I frequently had to wipe the front of my glasses down with my gloves, and it was chilly--right at the point where I was pondering to pull out my jacket, but not quite enough to motivate me to do it. Plus I was running late and didn't want to stop.
One of the things about riding in the cold--you can feel fine while on the bike because your core remains warm, but when you change at work, notice that your skin feels quite cold to the touch. After a few minutes at work, the chill starts sinking in deeper....I'm generally much colder 20 minutes after a ride than during. I may start leaving a jacket at work (where I am normally quite warm).
Did some mountain biking again yesterday, I was finally able to coordinate with my rother and get him on the trails again. We hit John Bryan State Park and did 8.5 miles or so, at roughly half the speed I commute to work. That's a pretty simple trail, and I am quite slow on it. I have concluded that it's hard to actually be bad at road biking, but it's pretty easy to be bad at mountain biking. It's still fun, though. Oh, and there were some very attractive women hiking. Maybe I should take up hiking.
Oh, on the way back I had to purchase gas. I was on the same tank from Aug 28 to Oct 11, so the driving less seems to be working for me.
