It's an interesting debate, for sure.
We are a family of 5, and we typically downhill ski 8 or 10 days a year in a good year. Plattekill is our favorite local place.
My wife and I nordic ski 3 or 4 days a week.
Our kids are 10 and 12, We usually get them a season ski rental for their downhill gear.
This year after looking at the downhill situation we elected not to get the kids ski rentals.
I don't envision us going more than once or twice.
