This seemed like the most appropriate place to post this. The call letters KNFL, which formerly belonged to 1470 AM in Tremonton and then 730 AM in Boise, were reassigned in March of this year to a (what else?) sports format station in Fargo, North Dakota on 740 AM. The "new" KNFL is home to the fifth biggest daytime AM signal in the country according to Wikipedia. I'm not sure, but I think the KNFL call briefly belonged to an AM station in Montana as well. Like the Beach Boys song says, "I get around"!
