Nice and cool. Low 50s. Blue sky. Passed a couple of women cyclists (not together) but overall I only saw one other bike. I think someone was trying to chase me but never got close enough to identify.
Oh and there was a sign next to the MUP saying "Trail Survey - Please Stop", and some college-looking people hanging out around a table with a drink cooler and stuff. I didn't stop.

Hey I'm commuting to work!

If they're there when I ride home, I'll stop and see what's up.
