I may try to get back out there after the summer ends. At the end of July we did the wounded soldiers ride which went from Amagansett to Sag Harbor and back, with an extened ride to Montauk. Sort of a figure 8 route.
Last week we did the north fork last week and managed to get in two short but nice rides. One was a 20 mile loop of Southhold, pretty much right off the town cycling map which combined their bay view and sound view rides. The other took us by ferry to Shelter Island, where we rode to Rams Head and back.
