Cycling 1:41:00  22.0 mi (4:35 / mi)
I had company on the ride home this evening. A science team colleague who works out of his house in North Carolina and visits the lab every few weeks brought his bike with him, as he sometimes does, and I think it was Florence who proposed that he ride home with me and she drive his car with the rest of our gear.
We were going to leave around 4 p.m. but we both had things that dragged on, then had to change and pack the car, and it was about 4:45 before we got started. Thoroughly dark about 45 minutes later, and it was a little bit hard to follow the twisty Sligo Creek trail but a lot of fun barreling through the darkness.
He's an expert mountain biker, and I keep trying to get him to one of our MTBO events, including this coming weekend, but it hasn't worked out.
