Today I went on a ride with Jaime up to Salem. Her father met us at a Starbucks just north of downtown. She took her bike to Portland with him this afternoon for winter storage.
The air temperature never went above 50 the entire ride and in fact in some places was probably closer to 40. A thick layer of fog that alternated between hugging the ground and hovering about 15 feet above the ground stayed with us all the way from Corvallis to Salem and back again. I added an extra layer of pants and an extra layer of long sleeve shirt today compared to what I had on Friday. It helped quite a bit. My only real problems were the periodic fogging up of my visor on the inside and the periodic moisture buildup on the outside of the visor.
On the return trip I was alone and was able to bomb back quite quickly. It seemed that the fog made traffic go more quickly than normal. The ride was about 80 miles total.
I took on fuel in Corvallis at 86.6 miles on the odometer before I left town. I paid $3.99 total getting 1.814 gallons. My fuel economy was somewhere around 47 mpg. This cold air seems to make it run a bit more rich than in the summer.
