Oregon has been having some beautiful weather for commuting; last week we even hit over 100 degrees F (I didn't commute on Friday, as I was returning from a business trip). But earlier in the week was great.
This week is cooler, which is quite nice. I wore a sweater this morning, but then took it off for the noon and late afternoon rides (got 17 miles in total). My bike is better now, as I've switched from down tube shifting to bar end shifting, and am really enjoying the convenience of not having to reach so far.
