By Trailways Bus
WFAS is located in the hamlet of Willow, 8 miles past downtown Woodstock. Trailways buses (800-858-8555) leave from Port Authority in NYC and will drop you off right on the corner off the farm. The fare is about $24 each way, and once you arrive in Woodstock tell the bus driver you wish to be let off at the intersection of the auto garage in Willow, 1/2 a mile past the white church. The farm's pastures are located behind the garage. The entrance is 35 Van Wagner, second driveway on the left.
If 2 or 3 dogs charge toward you looking like the hounds from hell, don't be afraid. They are just doing their jobs and want to smell you, and don't pet the big black one (Mio) right away.
Below is the schedule. Note that some buses terminate in Woodstock and do not go beyond to the farm -- taxi service is available if you reserve serveral hours IN ADVANCE at 845-679-TAXI (cell phones do not work in Woodstock).
