I think entres shouldn't be charged but charged the ones who come to look. Tey'd make more money that way after all we have to pay for the gas to go to these shows and in some cases that a lot of money depending how far you have to go.
For instance, there is a yearly car show where my daughter lives. It's 30 bucks for the weekend but I would only go for one day and still cost me 30 bucks regardless plus the gas would cost at least 60-70 bucks plus food etc.
I don't think so
