The last three days I've had to drive to off site meetings but finally got to commute in today. Actually I got a little fun ride in yesterday afternoon as well. Didn't check the temp before I left, but I'd guess low 50s F. High will be mid 70s. Commuting in street clothes now; jeans, t-shirt, hoodie and then a cycling jacket over the top. I still sweat a little but not enough to stink or require a change. Autumn is awesome!
