See if you can wrap your mind around this eye-popping price tag for a renovated college football stadium in Texas: half a billion dollars.
That's right, five years ago Texas A&M expanded and improved Kyle Field to the tune of $485 million. That equals more than half a billion in 2018 dollars.

That's more money than the gross national product of some small nations.
In fact, many universities in places like Tennessee, Kansas, Arizona and elsewhere are shelling out astronomical funds to build shiny new stadiums, or to make their existing facilities bigger and better.
A lot, if not most, of the money for these multimillion-dollar facilities comes from private donors, but the ultra-high numbers speak volumes about the role of sports in America's education system.
Sporting events, particularly football, have become cash cows that are critical to the overall economic success of many institutes of higher learning.
Even after adjusting for inflation, experts say the cost of modernizing or replacing aging stadiums is generally pricier than a generation ago.
Design and construction standards are generally higher.
And so are the expectations of 21st century fans.
They expect amenities like club level seats, premium concession areas, video screens throughout the stadium and robust connectivity.
Let's take a quick look at a few recent, pricey renovations along with some of their best features.
Making history with half a billion bucks
Texas A&M University
Stadium: Kyle Field (opened in 1927)
Location: College Station, Texas
2014-2015 renovation cost: $485 million ($514 million in 2018 dollars)
What the money bought: The latest renovation of Kyle Field was "one of the largest and most extensive redevelopment projects in the history of collegiate athletics," according to the Texas A&M website.
That's not surprising, given the final price: more than half a billion in 2018 dollars.
The project transformed Kyle Field from a horseshoe-shaped facility to one fully surrounded by seats, making it "one of the five largest stadiums in collegiate football."
It also boasts one of college football's largest video boards, measuring 47 feet by 163 feet.
For $400 million: No more wooden benches
University of Notre Dame
Stadium: Notre Dame Stadium (opened in 1930)
(Renovation included three new academic buildings)

What the money bought: Notre Dame called this renovation and new construction plan the largest building project in its more than 170-year history. The wooden benches are gone from the stadium known as the "House that Knute Rockne Built." In their place: vinyl-covered steel benches that are 2 inches wider, the South Bend Tribune reported. A gigantic 96-by-54 foot video screen dominates the south wall. The renovation also included a stronger Wi-Fi and cellular network, according to the school. But seating capacity dropped from nearly 83,000 to fewer than 79,000. Other improvements include new lights, a new press box and new accoutrements on the concourses.

What the money bought: Building the newest football stadium in the historic Big Ten Conference allowed Minnesota's football games to be held at a campus venue, instead of the school's previous, aging stadium, which was about a mile and a half away in downtown Minneapolis. "If you're sitting in the last row of TCF Bank Stadium, you still have an amazing view of the Minneapolis skyline. That's not always the case with the older stadiums," said the school's Assistant Athletic Director of Communications Paul Rovnak. "The West Plaza, which is the side that is closest to downtown, is an open space that's become a natural gathering space for our fans. We have tons of different food and drink options there."
