45F and a little bit of a headwind. I'd taken the weekend off. Still learning not to overdress... T-shirt, long-sleeved T-shirt, and light windbreaker. Took off the jacket 2/3 of the way through.
Saw a couple of other bike commuters... one lady I passed with a smile while heading downhill; she caught up with me at the last street interchange and blew past me on the uphills.
