There will be snacks, water and cupcakes (instead of cake).
It will be outside near the snake river, it will be hot out side so be prepared.
There are public bathrooms, I haven't used them so i don't know how clean they are.
No parking or driving vehicles on grass, sprinkler heads, sidewalks, or valve boxes. No glass containers. No fighting.
you should be able to take photos and put them on the folder for everyone to see.
