Yeah I went to a Smackdown house show in Hammond Indiana maybe a year and a half ago and it wasn't packed. They just had the wrestlers walking from behind a curtain. No presentation at all. It was like a low level indy show look. Still good matches.
And Dec.26th is a Smackdown house show in Chicago. At the same place they just did the sold out LIVE Raw show.
I don't see the small level house show selling it out. Might still attend though.
