For clubs as in dungeons or Nightclubs might I suggest that Google is your friend. Type in BDSM and the name of the city or town you are looking around.
When I was first introduced to the lifestyle, the closest dungeon, and realtime people I could find, was in Atlanta, GA, a 4 hour drive for me. I made that drive many times in those early years. I was willing to drive 6 hours to Birmingham, AL and over 20 to groups and clubs in Texas (or pony up the money to fly out there).
The number of groups has proliferated over the years, they are cropping up everywhere. You'd be surprised what you can find if you look hard enough. Or travel far enough away. In Atlanta I met people who were closer to home... in their groups I met people that WERE from home... And after a couple of years of traveling I started my own group and they celebrated 10 years last August.
Who knows what you can do with a little exploration and determination?
Vermont:
# Rose & Thorn Northern Vermont BDSM Parties; This is a friendly gathering of people who are active in the Dominant/submissive lifestyle. This is an opportunity to meet friends (and singles) who are on the same page. This is NOT a "play" party but an opportunity to build a community of like-minded people.
# Vermont Society of Kink; holds a Soiree the First Friday of each month as well as a popular online discussion group.
And I'm not going into all the groups in New York around Albany and northern New York... There are plenty of groups within an hour or two of your location. Get out there and meet them.
