Oh yay. We're starting to see dates for 2010 rides. This gives me the motivation I needed to get off my butt and start training.

April 24 - Ride to End Hunger in Calvert County
June 12 - Patuxent River Rural Legacy Ride

Links are not up to date yet, but it's a start.

I also checked the Baltimore Bike Club but they don't have a date yet for the Civil War Century. My guess would be Saturday, Sept 11 since it's usually the same weekend as the Indian Head Century.
