Winter Snowboard/Ski Trips (Optional). As soon as the weather cooperates and we get snow, Dragonfly offers the opportunity to ski or snowboard each weekend at Mt. Shasta Ski Park. These trips are a great opportunity for students to get out and participate in healthy outdoor activity throughout the winter. To be eligible to attend, each student must complete 80% of their weekly check sheet. If your student has ski or snowboard equipment and expects to go this winter, please send that equipment to Dragonfly, as it will greatly reduce the cost of skiing or snowboarding by eliminating the rental fee.
