EDIT: this is in response to Harvey's question above
WIndham has been my home mountain since 1984. I have a pass, but am still planning on hitting Plattekill this Friday depending on how the week plays out. When we're up at the house, I'm locked into either Plattekill or Belleayre as alternatives to WIndham depending on local weather and snowfall variations. When we're not up at the house, I have some leeway in making day trips, usually deciding the destination close to the day. For example, last season I ended up hiking Windham 4/20 after the big last season storm we had; hiking Plattekill and even driving up to Gore or Whiteface were also options. Last Monday I had MLK Day off and made a last-minute decision to head to Mohawk Mountain in CT for the first time. Ended up being a great day with excellent snow coverage and conditions. I imagine it must be really fun when it's 100% open. Definitely rode bigger than its actual elevation and vertical drop. When I eventually retire, I'll be making more last-minute choices based on the latest weather and conditions.
