All of the day goings-on are really great. For instance, the Saturday we were there they had a vintage car show. And Sunday night they had the Thunder Dome (Motorcycles in a sphere). Those things were really fun.
For the night show, I was kind of expecting, oh I don't know, an EXPERIENCE. We were there for hours and all we ever saw were basically commercials on a giant, overhead tv screen. A very entertaining giant overhead tv screen, but not worth the neck strain.
I'd recommend avoiding going there at night as it gets overly-crowded.
