Welcome to Rockport, MA.You will need to park on the street at a meter, and walk down Bearskin Neck to get close to this cache.
Do not park on the Wharf as the local parking troll may apply brightly colored to your windshield, or make your car to a magic trick involving a vanishing act.
The cache is near the red building you see near here, but is not difficult to find. The given coordinates are off by just a few feet to you may have to look around just a bit (the geocaching site only permits three decimal places).
Fishing shack was built in 1884 and purchased by the Town in 1945 as a monument to Rockport veterans.
Beware of Muggles in the area.
The cache is a small plastic box, but it may make you a while to find the cache. The USGS Maps of the area are off slightly, so if you look at the cache location on some maps it will show it as being 25-30 feet out into the water.
