For the most part, the mountains & hills in the US get ample snowfall for 3-5 months each year.
The places that don't get snow, generally speaking there just isn't enough demand to support a dryslope/fridge.
Even at a modest $3M investment at $30 per head you'd need to bring in ~60 people per day, 365 days per year, to break even and that would still take 5 years!!!
And that doesn't account for things like taxes, insurance, wages for your employees, utility bills, maintenance, etc.
The one positive thing about the NJ place is it could get a lot of people. ~20 million people in metropolitan NY, plus you could get tourist from NYC.
