People living in nyc, where do u go to ski

Not near, but usually I fly out to Vail whenever I have the time 

Many mountains in Vermont (4-6hr drive, some shuttles leave from NYC I believe).

Some smaller mountains in NY, MA, etc.

Hunter and Windham aren't too far

Killington VT or Hunter NY

Hunter and Windham leave a LOT to be desired, but are the only ones really doable for a day trip - about 2 hours from NYC. Good if you just love to ski and want to get out there even if the snow is kind of bad.

Vermont is decent skiing (take your pick but Stratton, Stowe, Killington are all popular) but that's gonna be a 4-6 hour drive and it's not easy driving. There's a train, kind of, but it's old, smelly, no Wifi and takes like 6-9 hours so would not recommend that. VT is reasonable for a 3 day weekend. 

Obviously CO / the west in general are better but that's not realistic to do more than 2-3 times a season, the above two places will keep you on the snow even if not the gold standard

The restroom at most restaurants is sufficient
