How do animals in a forest play bingo?

My grandmother in law died recently, which meant that a family tradition has come to and end. When my wife and I would visit her, we would go to her apartment, take her out to dinner, and then my wife and grandmother (and sometimes I) would play bingo at the Sunset Station casino. Always the 7:00 pm game, because they had a triple-whatever reward. Not that we ever won, but it was something that we did. (Incidentally, I briefly mentioned this in my business blog once.)

In addition to the family issues, the game itself has an interesting appeal, which means that I have occasionally mulled over the idea of playing bingo at other locations. (And yes, I am middle aged. You probably didn't have to ask.)

Well, one potential place to play bingo is at Ontario Elks Lodge 1419. Liset Marquez posted the details:

Ontario Elks Lodge #1419 has Bingo every Wednesday Night.
Doors open at 4 p.m. and the games begin at 6:30 p.m.. There is food
service and a large open room to play in. K.D Ische is the caller.

Now this is not like cow chip bingo, and presumably is a little different than woman's club bingo.

But there's one thing I can't figure out - how does an elk hold the bingo card?
