5.3 miles – fast – hilly.  Info: Tammy, 631-896-1409, between 6-9pm. We’ll do the first few miles of the Nassau-Suffolk Greenbelt Trail by continuing past Route 108 to Stillwell Lane, then we’ll turn around and retrace our steps.  This trail has some nice hills to make sure we get a great workout.  This is not a beginner hike.  Bring water and trail snacks, and a hiking pole is recommended. Heavy rain cancels, light rain may not; call morning of hike if unsure.  Directions: We’ll meet at the Nassau-Suffolk Greenbelt Trailhead on Harbor Rd. (NY25A), in the unpaved parking lot adjacent to the Cold Spring Harbor Library. Hike end time is approximate.
