Best commute ever for me! Temps of 72 degrees compared to 104 yesterday. I felt like I pedaled more and used the motor less because I felt more energetic, yet I made the 17.5 mile trip in an hour and 15 minutes, which is five minutes faster than before. And this is the first time I've commuted by bike all four days!
I even saw two cyclists going the other way on different stretches -- I usually see a cyclist about once every three or four trips but I'm seeing at least one every trip. I think fall is going to be a great time for commuting by bike!
