We are a group of snow skiers who pool their resources to ski at group rates. Most members reside in the greater Pittsburgh Pennsylvania area. Some live in other areas around the country. Dues, which support our newsletter, are $15 per year for individuals. $25 for families. Our membership is fairly evenly split between individual and family memberships. We have about 300 members. The average age of Der Sitzmark members is a bit over 40, although the actual range is from 21 to 80+. Those under 21 must be be part of a family membership and are only permitted on trips if their parents participate on the trip.
