I played for about two hours, winning twice late. I ended up with a jumbo ballpoint pen (my wife said that it would be a much better prize if the long plastic cylinder took batteries) and a set of dollar store BBQ tongs. I also lost $15.50 playing, but it was a lot more fun -- because of the social aspect -- than the bingo game I'd played on my computer in December 2005, which I'd described as "a pointless, mindless game. How can the old folks find this stimulating?"
Ironically, my dad stopped by the bingo room partway through the fair, and although I offered to buy him a card, he replied "nah... I'm not old enough to play bingo yet.". Touché.
