I think there are several errors in the map here.  (1) Pulpit Rock Road is a single road off of Thomas Pond Terrace, not the double road shown here. In this map, the one bearing the Pulpit Rock Rd legend is the "wrong" one, although I think it starts in the "right" place (or closer to the right place) than the other Pulpit Rock Rd offshoot.

The second error is in the location of 22 Thomas Pond Terrace.  That property is located closer to the start of the lake and is actually on Thomas Pond Terrace, not on Pulpit Rock Rd. 

Third, There are no side streets off Thomas Pond Terrace after the start of the lake vs. the two shown on the map.

Fourth, the location of the #31 Pulpit Rock Rd. is wrong.  House 31 is at the end of the incorrect/truncated Pulpit Rock Rd (Pulpit Rock does go to a cul-de-sac).  Locations for 33 and 35 appear correct.

For what its worth, there is also a small island in Thomas Pond at the end between 33 Pulpit Rock and Thomas Pond Terrace that is not shown on the map at all, and another one in Flag Cove at the northern end of the lake

Thanks, hopefully this helps you improve the maps.
