Bike the Cape Cod Canal trail from the Cape Cod side after having lunch at Seafood Sam’s on Thursday, at noon, before the official start of the Cape Cod Weekend.
The restaurant is near the power generating plant at 6 Coast Guard Road in Sandwich Ma. 

Cycling is casual, self-lead, weather permitting, and w/o a sweep. Don’t forget, water, spare tube, and helmet. Good news, trail is flat, but watch out for head winds.
