Bring a warm jacket. This is an outdoor event in the Pacific Northwest. Over the last 20 years, daytime temperatures on May 30 have ranged from 52 to 79 F. It could be shivering cold and rainy, or pleasant spring sunshine. The shelter and the walkway to it are paved, but the event parking is on grass which could be mushy, and the drive is gravel. There are two accessible parking spaces.
