If you want a lot of pinballs at the show then you will have to provide an incentive for people to bring them.
The best incentive for getting people to bring pins to the show is for selling them.
Most shows of this type, like gun shows, are centered on buying and selling.
The problem with people bringing games just for the heck of it is that a lot of these games are very valuable now and trucking a few $3000 pins to a show so other people can bang on them for two days in exchange for a $17 ticket is not much of an incentive.
I was there on Saturday afternoon, there were so few games left that we just hung around for an hour and left. My wife wanted to try out the truck stop, couldn't get near it.
