Moparty
I have attended for the past 2 years, and am going to be there this weekend. One thing I remember is that the entire event is staffed by Holley employees. They are people that work at the Holley manufacturing plant as engineers, production & office workers etc. They are always very friendly and excited that we are there for their event. For them, it might be a nice break for a few days to get out of the normal grind.
That said, some of the event wonky-ness might be to help these employees be able to navigate running an event, when they are not seasoned "event people".
