I forgot the math and I'm too lazy to do it again, but given the size of the Fargodome relative to the size of Fargo when the dome was built....the Fargodome today would have to be built for 35,000ish.
....there's no doubt a new stadium is needed in Fargo, if not today, tomorrow....and they could be making a big mistake the longer they wait.
Keep growing and winning games...all a program can do. If an FBS invite comes down the road; great, evaluate.
