Naked in Nebraska: a wrestler's story

Anyone know what college or university this is? Why do they have to get completely naked for the weigh-in? Not that I'm complaining, but it surprises me that they're not allowed to keep their underwear on given how prudish most straight jocks are about being naked around other guys. They're trying to make a certain weight, R You can't wrestle in your weight class if you don't make the weight.
