Take Rt 8 north towards Speculator. Turn right onto Rt 10. The end of Powley Road (it might also be signed as Piseco Road) will be about a mile down Rt 10 on your right. There should be someplace to park there.
I would suggest joining Salsibury Ridgerunners Snowmobile club. From East Greenbush your roughly about the same travel time & distance. (I'm in Schodack and it's usally about a hour and a half). They have a big parking lot, club house with a decent bar and kitchen and the trails are usally very good. The club house is not to far from the south end of Powley Rd.
