BikingOnCanalSpring on Wheels Along the Potomac SORRY CANCELLED/RESCHEDULED
Friday, May 6 (8:30 am-3 pm)
Leader: Stephanie Mason
Members $30; nonmembers $42
Spring has sprung and the towpath along the Potomac River is one of the finest places in the DC-metro area to experience the season’s richness. In order to cover more territory and visit more habitats, we’ll use bikes to explore the stretch from Swain’s Lock to Riley’s Lock, a 12.3 mile round-trip ride. We’ll dismount often to look for spring wildflowers, butterflies and other insects, and reptiles and amphibians, all the while keeping an eye and ear open for spring migrants and other breeding bird activity. Bring your own bike.
