It is Plattekill’s- or was last year at least. I assume it’ll be the same this year. As far as I know, there’s no sanctioned skinning at Belle. Windham, believe it or not, seems to be the most open to uphill traffic in the Catskills.
I don’t know about Cortina. Is that the place right next to Hunter?
