It's at the funeral home at 800 N and 600 E. It starts at 5 and goes to around 8 or 8:30. I've been going since they started several years ago, and it's always really good. It will be really hot today, but there is shade you can escape to for a bit.
Also, you may want to wear a mask. If you're one of those types who refuses to on principle, they may also be handing out brochures about their funeral services. (that last part was a joke. Ha ha?)
