@ShortSideOption beat me to it, but, yes, USD is a D-1 school now.
I went to college there in the 90s, and there were a lot of students at that time from Nebraska, but that number has really jumped through the roof since then. They built a bridge across the Missouri right beside Vermillion in the late 90s, which saved some people a couple hours of driving if they lived straight south of Vermillion. Also, while South Dakota's tuition has risen over the past few decades, it hasn't risen nearly as much as Nebraska's. A recent student of mine is finishing up her undergrad at UNL this year, and I about had a coronary when I saw how much she was paying out of state. When I looked into it (this was four years ago), the in-state tuition for UNL was just slightly less than the out-of-state tuition for Nebraska kids to go to USD. If a Nebraska student lives closer to Vermillion than Lincoln, it's probably cheaper when you factor in housing, travel, parking, etc.
But Vermillion. Your argument is invalid.
And the Cherry St. Grill closed.
