To get from East Hampton to Sag Harbor, many would opt for route 114. Though, probably the quicker route during low traffic times, I have been directed via GPS to take Swamp Road on two separate occasions and have welcomed the change of scenery.
You have to be careful on Swamp Road....it's very VERY curvy, but that's most of the fun. This morning while driving to Java Nation, I felt as if I was in a Mario Cart game. Anyway, the houses are mostly hidden but I found a couple (including this one) that managed to show their faces to the other Swamp Roadsters.
