Cross-country skiers who use the Quarry Road Recreation Area in Waterville are being asked to donate money to help cover the cost of snowmaking. As part of the program, skiers would receive stickers for their vehicles based on three donation levels: $100, $50 or $20. A daily voluntary fee for ski trail use is $5. City councilors last week voted 6-0 to approve the voluntary fee schedule, which came recommended by the group The Friends of Quarry Road. The Morning Sentinel, reports that group secretary Caroline Mathes says the goal is to raise $30,000 annually to support the snowmaking budget and is an effort to avoid a mandatory fee schedule. Quarry Road is a city-owned, 200-acre, four-season recreation area for hiking, bicycling, walking, snowshoeing and skiing.
