I went by SCSU's new Husky Stadium a couple weeks ago, and while I truly believe it's a million times better than Selke, they really should've at least built the first phase to seat 6,000. I'm a stadium enthusiast (currently studying architecture), and hope someday to design stadiums and arenas, so I was able to get a good idea on how it was design-wise. It's very nice looking and clean, but again, too small.
Even if the budget was a factor, I would think that SCSU could build a 1,500-seat or so visitors side made of metal bleachers. You'd be suprised as to how relatively inexpensive you can set something like that up. But even with something like that, there's bound to be not enough room for UND fans making the trip down to St. Cloud. The Bison had over 2,000 NDSU fans at Selke's last game last year, and I'd think there'd be around that number of Sioux fans at the game.
Seeing that the past SCSU attendances have basically been sell-outs, the higher-ups there are going to have to do something about the seating shortage right quick.
