I will echo what everyone else has say about which days the show runs. I've made numerous other posts on this topic which seems to come up every year.
This is the first time I'm missing the Ohio show since I started going in 2008. If it was Fri-Sun, I would go for the whole day Saturday and stay for tournament playoffs and half day of the show / breakdown on Sunday. It would be a huge draw for both locals and travelers if Saturday ran all day and into the night.
