Just off Route 57 near the Agawam/Southwick border. The white blazed M + M trail heads north from here.
Rocks, roots, snakes, ticks and a little up and down.
You may need tweezers.
Final cache container is a small lock and lock.
At the coordinates listed you MAY find a small tube with the final coordinates. N42 03.XXX W72 42.YYY. The final should be far away that you won't stumble on it, I hope!!
