The towns of Ancram, Copake and Hillsdale will sponsor the fourth annual Roe Jan Ramble Bike Tour, a fun, noncompetitive ride that aims to promote biking in Columbia County. Riders again will have the option of raising pledges to help fund the Copake-to-Hillsdale extension of the Harlem Valley Rail Trail. Riders have their choice four courses depending on their level of biking ability: 10, 25, 35 or 50 miles.
