Cool, actually. It was in the mid-70s, but things have heated up enough that temps like that are very pleasant to ride in. I drove yesterday (had to make a large purchase at a store near the office), but an office mate rode. His wife rode from home to meet him in the afternoon, then they rode home together. She didn't make it; the heat got to her and their son SAG'ed her home. (She's okay now).

So I'll be doing my minimal-hill/maximum-shade ride home this afternoon. This may be my first 100+ commute this year.
