Windham is the Best Ski resort within 5 hours of NYC (It is about 2.5 hours). Killington and Stratton are bigger with more vertical but Windham compares very favorably with Okemo, Mt. Snow and other big name ski resorts. It blows away smaller places like butternut and catamount etc... I have been there twice this year so far and conditions have been excellent due to top notch snowmaking. Windham also has an adventure park with snow tubing and ice skating.
