I'll be passing by InZane in the cage

on July 31 on my way to pick up my daughter from Grandma's house. I could arrange the travel to get up to Johnson City Thursday afternoon, spend the night and then boogie up to PA on Friday.
Is it worthwhile to stop by for a couple hours or is it mostly riding/socializing destination?
The website indicates "Groundzero" is a Holiday Inn. It appears there will be vendors, so I was thinking a hall or small convention center of some type?
Thanks
Jim
