What a interesting little cemetery! Right off Rt 106, this small site holds an array of Syosset/Jericho, NY's first families. These Quakers were quite prominent on Long Island in both business and politics.
Feel free to read the headstones as most of them are quite old. Many are weathered down to nubs.
Cache is a typical LI hide and should be quite easy.
Good luck and have fun. Don't forget your stealth in the car...
