Pi = Pie is a free event, but if you've got a few dollars to contribute we're collecting funds for ALS Ride for Life.
ALS Ride for Life is a patient driven, largely volunteer organization, whose mission is to research funds to find a cure for Amyotrophic Lateral Sclerosis (ALS), support patients and their families through patient services, raise public awareness of this disease, and provide the community with the latest news, information, and inspiration.
