51 degrees F is about perfect commuting weather. I have not rode to work for 10 days becuse I had teeth pulled and other things till Friday. So Saturday I took out my road bike for a 15-20 miler and my back hurt a little (fit problem) so later saturday I cut down a lot of brush down a fence row and by dark my back and knee really hurt. So I road today, my knee still hurts when walking but not at all while riding. Makes me mad I did not ride sooner, I think my knee is fine to ride on.
Sorry to type so much but I am at work and trying to look busy. Think it is suppose to be low 60's on way home.
