Crazy Gramma Traditional Cache

This cache is hidden close to "the lakehouse", where Crazy Gramma kidnaps the Mathews With 1 T boys for the weekend. The lake itself is a small, man-made lake, perfect for weekend getaways. Right by the cache is the UGL beach. During the summer, the lake is busy with people swimming, fishing, waterskiing and relaxing. 

If I see you from the lakehouse, I'll stop over and say hi. 

The location is a small memorial for a couple, who I can assume, had influence in the Upper Greenwood Lake Association. A plaque nearby has their names on it. Have a seat at the bench and watch the brook. You can park in the lot or on a sidestreet and walk over. 

Cache is a small (not tiny) container with room for swag, TBs and such.

Please try to put this back right where it was. The hint leads to a specific "type" and wouldnt make sense if the cache wasn't put back there.
