The shuttle stop is "Tristam's Landing". Just cross the street (opposite the Madaket harbor sign) into Cambridge Ave, make a right at the first street, which is Arkansas Ave. From here it is about 50 yards and you come to a series of mail boxes on your left (there is one which looks like a fish). Make a right and you come to parking lot. You pass a few houses east of the parking lot until you see the "FLY INN", house No 38/473. Your entry is from the front porch.
