I think what Wyoming is trying to do is cater to the people in Northern Wyoming moreso than Southern Wyoming. However, there's no where in Northern Wyoming big enough to host a Cowboy basketball game besides Casper.. so they shoot for there, a more central location, easier for people from the Big Horn Basin, Sheridan, and from the northeast corner. Mostly speculation on my part, but that's my guess. However, if they really wanted to appeal to Northern Wyoming, they would play a game against Montana or Montana St in Billings, which drew fantastically last time I went to that border war game.. the Metra was packed, mostly UW fans. So a game w/ SoDakSt/USD would be fine, but ultimately, not the audience UW is looking to appeal to.
