If this darned cold snap is gone by then, I'd love to do a group ride on the C&O on the 15th. I did 21 miles on the paved W&OD on Tuesday (glorious weather that day, too bad it didn't last!), and as I was crossing over White's Ferry on the way home I decided I just had to get in a few miles on the C&O, too. So I stopped and did about 5 miles before the sun set.

Riley's Lock either upstream or down is a nice ride, though it can be crowded. Depending on how much driving you guys want to do, we could start farther upstream.

And speaking of mtb, I want to give that a try this year. Has anyone ever taken one of these classes? --> The Bike Lane: Women's Beginner MTB Clinic
