[Sitzmark Ski & Social Club - Home Sitzmark Ski & Social Club of Minneapolis and St. Paul is a registered non-profit activity club based in Minnesota. We are an adventurous bunch and like to keep active, socialize, and travel. We welcome single people and especially encourage married couples to join us. Ages in our group generally range from 25 - 65, with the majority tending to be 40+, active, health-conscious working adults. Sitzmark has hundreds of members from the Twin Cities and surrounding areas, even as far away as Switzerland. Because we plan events all year round, we provide singles and married couples many opportunities to meet and make new friends through a wide variety of activities, such as skiing, golf, biking, tennis, social activities, and trips.]
