Hi Ry - I XC ski also, but have not been out this either. I usually ski bushwack style in Wawayanda or Harriman, but those need close to a foot of snow because of rocks. If we should get 4 inches or so, I hit the local county golf course. Snow gods are not with us this year.
If you are lookibg for a groomed track for skate ski, there is Minewauska and Fahnstock, both NY state parks that groom a track if there is natural snow. Mohonk House grooms too, and has 40 miles. I have not been, but have heard good things about Garnet Hill in the Adirondacks.
Happy trails, by bike or ski!
