Go Figure! in the Hamptons Mystery Cache

Another quiet Hamptons park-spot looking north over the golf course below. It is at the intersection of three trails with a park bench to rest and enjoy the quietude and view. On-street parking is nearby: 1) 45m West of the cache or 2) 36m East of the cache.

CONGRATULATIONS to HuntHikers for the FTF on this snowy May 12th!

NOTE: THE CACHE IS NOT AT THE POSTED COORDINATES.

Use the numbers corresponding to the letter in the boxes to complete the cache coordinates.
