Back in the day...not that long ago it seemsYes, the shows were cash only. I have fond memories of bringing only a set amount of cash in order to limit my purchases. And then running multiple transactions on the ATM machines at the shows because they would only give out $200 at a time. And at the bigger shows, the ATMs would run out of cash and someone would have to be called to come refill them. While you waited to see if what you wanted to purchase got snatched up by someone that still had cash. Good times!
But they really were good though. Everyone hung out and talked and got to know everyone else and phones were not a part of it at all.
