This monthly ride has been happening in Morristown since 2007. Meet up at Morristown Town Hall Parking lot for a short, flat and easy ride for riders of all abilities. The ride leaves town hall, rides down South Street, takes a spin or two around the green and then heads down to Sussex and then loops back to the Morristown Green and to Town Hall.
Bring lights if it is still dark out and maybe some cash for after-ride bite to eat or drink.
