The event in 2020 was unfortunately cancelled, but due to your generosity we were able to give backpack buddies $4550 to help provide food for children in need. However, due to the nonprofits nature of this event and the purchasing the hats and metals ahead of last years event but being unable to hold it, we will be using last years hats and metals this year. We thought it was best to help others and use last years hats and medals as a final send off for 2020. We will happily provide Sharpies to everyone if you would like to change the date to this year. We apologize for the inconvenience, but hope you understand.
