No.
I don't really know the guy other than seeing him at his Tulsa shows.
IIRC, the last time I setup on the other side of the table was at ones of his shows.
I've heard more about him on this site than anywhere. The only negative thing I can personally say about him is the admission to his shows (he's not the only overpriced promoter), but I remedy that by no longer attending. I will say that over the last several shows, his are my least favorite.
I hope to hold out but sometimes I gotta get my gunshow fix.
Met him in person at F-Class match - nice guy. The only gun show I go to is Wanenmacher - so I guess his business has no affect on my opinion about him. I prefer to make my own decisions about people - not what "internet" told me.
