Plattekill Mountain is located in Roxbury, NY- just three hours North of New York City and offers the service of renting their entire mountain for just $2,500 a day. (Thats $100/day for 25, or just $10/day for 250 people).
Plattekill has 1,100 vertical feet of terrain, 38 runs, a terrain park, tubing, and gets an average of 175" of snow each season.
So any Monday- Thursday during operating season get your office, friends, or birthday party together and take advantage of this. Better yet book it on a powder day and skip the lines and gapers to enjoy this place all to yourself.
Next NS Gathering? I'm thinking yes!
