At the published coords there is parking for several cars and a yellow sign on a pole.
If the number on the sign is 100, the final is at N 42 47.074 W 071 03.724
If the number on the sign is 50, the final is at N 42 47.309 W 071 03.946
This is an easy multi for my first hide. Be sneaky, there are often lots of muggles around.
