As you enter the park look slightly to the right. You will see two benches in front of two trees preceded by a small garden with a stone. As you walk in, sit on the bench to the left. Mark your position and project a waypoint 369 feet 23 degrees True. This will give you the coordinates for the Final stage.
Webb Memorial State Park is a Massachusetts state park located on a peninsula that extends nearly half a mile into the Hingham Bay area of Boston Harbor. It is composed of three connected drumlins and a low marsh area. Although not itself an island, the state park now forms part of the Boston Harbor Islands National Recreation Area.
In the 1860s the peninsula became part of the Bradley Fertilizer factory, and was used for dumping industrial waste. In the 1950s it was used to house the missile launchers for a Nike missile site. The IFC (Integrated Fire Control) and radar systems for this site were located on what is now Spinnaker Island, on the other side of Hingham Bay. The missile site was deactivated in 1974, and in 1977 it was transferred to the Commonwealth of Massachusetts and work started on its conversion into a state park. Webb Memorial State Park opened in 1980.
