T-shirts are part of the registration costs however if you would like to consider donating $10 to your registration to help cover part of the cost of the shirts, that would be greatly appreciated. This is not a requirement to get a shirt.
If you want to make any additional donations, there will be an option at checkout to do so. Any additional donations will go to Big Sky Autism Project and HEARTism to help spread awareness and continue to provide services to the state of Montana.
