You market to your audience

I spent this past Friday and Saturday in Pocatello, Idaho (oh joy...)
I paid attention to the advertising banners and sponsers in the Holt Arena (where their track is) at Idaho State University.

There were advertising banners thru-out the complex, just like at most sport events. I noticed an interesting theme among these banners. This is just a small sample of the banners:

-Got milk? Idaho DairyMan Association
-Simplot (Idaho potatoes)
-Farm Bureau of Idaho
-Heinz ketchup
-Idaho Lottery
