Go jump in a lake! Okay, if it's for a good cause. Freezin' for a Reason- The Polar Plunge for Special Olympics Alaska is a PLEDGE DRIVE. The goal is to ask friends, family, co-workers, etc. to pledge for you to show their support for Special Olympics Alaska as they encourage you to take the plunge into Goose Lake. The minimum amount of pledges raised must be $125 per plunger; however, please consider raising more to support the sports and training programs for Alaskans with intellectual disabilities.
