I have to admit, during one trip to Vegas there was a show at the Plaza the day we flew home. Sooooo...being a collector, whose mission is to collect...I did sneak into the showroom during the set up, the day before the show opened!! (It was just to see one dealer, and her shop notified her by cell phone that I was coming. I ogled other tables as I went past them, but was afraid I'd be reported and get into trouble if I tried to buy from anyone else! )
