Wow I cannot believe that website has Red Jacket Ski Hill!!
http://www.nelsap.org/ny/redjacket.html I grew up down the road from this place, it had been closed damn near as long as I can remember. We used to go sledding here in the winter, until we usually got kicked out by the guy who lives in the old lodge. Was a cool place to go in the summer to as it had a great view. There is a creek and waterfall with a old mill at the bottom of the hill as well. There is not much left of the ski lift or the mill, but next time I am out at my parents house I will have to take a walk down there and take some pictures. Happy to see it was included in the database!
