BRISTOL, Tenn. — One of the coolest things about this classic American experiment is the language people have wound up using. At one point, Adam Rust of the Bristol Motor Speedway stood at football field-level and said, "Come game time, this infield will be full, with seating, premium areas on pit road."Next, he said, "The bands will be down on pit road."Later, Jerry Caldwell, vice president of the speedway, said, "Virginia Tech's band will be in Turn 1, and Tennessee's will be in Turn 3."In this visionary landscape, they will play college football on Saturday night at a racetrack — its grandstand expected to swell with 150,000 people, the most ever to attend an American football game — and they're talking marching bands on pit road.Then there is the answer to what everybody has wondered: In a structure huge enough to have just held a NASCAR race on Aug. 21, aren't some of the seats going to prove uniquely terrible? Must some fans bring along, not necessarily binoculars, but a telescope?Sure, to come around the bend from the highway to the south and spot Bristol Motor Speedway on the right is to half-gasp. The "Last Great Colosseum," as they call it, is one powerful sight. Yet to walk in — or, well, ride in a car in — feels different. It's more than enough of a bowl that it gives the impression that it is a football stadium."We're a football stadium on steroids, that's what I say," Caldwell said. "And it's really what we are. It was fun early on in the three-year process to see that kind of confirmed by the folks at Tennessee and Virginia Tech that had not been here before. When they came into the facility, they were blown away like, 'No, this is great.''' Rather like an English Premier League soccer match, fans will sit mostly segregated, between fan bases, except they'll be roughly half-and-half. The speedway's bowl shape should allow for consuming noise, a byproduct proven year after year with racing.But there's a big distinction. Said Rust, "I'm excited to hear 150,000 fans cheering for two teams."He said, "We're used to those fans cheering for 43 different teams."And so: "And so the concentration of the noise will be, it'll be mind-boggling to hear that. I can't wait."And: "Just imagine, the entire backstretch of the stadium is cheering for the University of Tennessee."The front stretch, for Virginia Tech.
