During the week, Tannersville is a quiet little Greene County village that looks much as it did during its Catskills heyday, when the mountains were studded with Dirty Dancing-style resorts. On weekends in winter, the 500 or so residents are joined by swarms of skiers, snowboarders, snowmobilers and other snowy-activity enthusiasts who drift into town after disporting themselves at Hunter Mountain, which is a few miles up the road. On summer weekends, the town comes alive with bikers, hikers, and various outdoorsy types, along with a raft of low-key second-homeowners.
