I always thought it would be interesting if Boise State, the City of Boise, owners, investors, donors, etc.--with a smorgasbord of money from funds already allocated for stadium renovations, plus a local option sales tax, plus private money raised--somehow all came together to build a fractionally-owned, state of the art, 40,000-seat new stadium for Boise State football, a pro-soccer team, the Idaho Potato Bowl, concerts, events, and urban amenities dotting the surrounding stadium, right on the Boise River close to downtown/campus. Perhaps you could have a turf-swap system similar to University of Phoenix Stadium, switching between a blue football field and a FIFA-certified soccer field.
One possible location would be across the street from Albertsons Stadium (where the Chili's, glass office building, etc. is located). It would require acquiring a lot of land and razing a lot of buildings, but this location is close and easily accessible from the recently built athletic complex and training facilities, and would free up prime real estate on campus for classrooms, student housing, and other planned facilities in the Boise State campus master plan.
If all these stadium-building/renovating resources could somehow be consolidated, you could build a cutting-edge venue with state-of-the-art amenities that all parties involved wouldn't be able to fund independently.
Fun to think about.
(doesn't have to look like that, but I love that design, it's one of my favorite stadiums)
