The rest of the country may equate the dawning of each spring season with mid-March, the blooming of flowers, warmer temperatures and the smell of new-mown grass. But for the millions of diehard NASCAR fans in the U.S., spring starts a month earlier when the acrid smell of car exhaust and the booming, crackling sounds of 750-horsepower engines capable of reaching 200 mph fill the air of central Florida.

Welcome to Daytona Beach, Fla., where for more than 50 years NASCAR has reigned as the supreme king, first racing wildly on beach tracks made of sand, and then on the high-banked 2.5-mile oval superspeedway that has given racing fans a roller coaster ride of emotion -- from edge-of-the-seat excitement to the numbing pain of overwhelming grief -- for more than four decades.

Daytona International Speedway is the official name of the place, but almost everyone refers to it simply as "Daytona," signifying the racetrack and race that made it famous and put the city of Daytona Beach on the map: the annual season-opening Daytona 500.

The undisputed shrine of stock-car racing, built by NASCAR's founding family, the France family, DIS has spanned the gamut of highs and lows. It's where legends such as Richard Petty, with his record seven victories, enjoyed some of the greatest days of their racing lives. It's also the place where tragedy struck down arguably NASCAR's greatest driver ever, Dale Earnhardt, on Feb. 18, 2001, a pain that still sears through the hearts and minds of the sport's most rabid fans.

But perhaps more than anything, Daytona is a celebration of sights, sounds and Americana at its finest. The multicolored cars and accompanying uniforms worn by members of each team, the people watching of celebrities and average Joes and Janes alike, the flag-waving patriotism, the flyovers by military jets prior to the start, and the hopes and prayers of the nearly 300,000 fans in the stands for an exciting yet safe race make every Daytona 500 a microcosm of America at its proudest and finest.

"The Daytona 500 is our Super Bowl, Major League Baseball's All-Star game and the Indy 500 all rolled into one. It's the one race everyone wants to win in Winston Cup," said veteran Mark Martin, driver of the No. 6 Ford, and who is still chasing his first victory in the Daytona 500 even after 20 years of racing on the Winston Cup circuit.

Added fellow Roush Racing teammate Jeff Burton, driver of the No. 99 Ford, and whose older brother Ward won this February's annual Daytona 500 renewal, "Even if you don't win another race in your career, if you win the Daytona 500, you'll forever be known as a Daytona 500 champion. That means that, at least for that one day, that one race, you were the best of the best."

The late Dale Earnhardt had perhaps the most publicized love-hate relationship with Daytona. He chased the checkered flag for nearly 20 years, only to come away each time disappointed and out of the running. Finally, on his 20th try, Earnhardt won the one race that had eluded him throughout his career, becoming a Daytona champion in 1998.

"No one ever remembers you for finishing second at Daytona," Earnhardt said after winning the elusive final feather in his racing headdress. "It's an all or nothing deal. It's the only race where if you don't win, you start thinking about next year's race right after this one is over. You basically spend the next year preparing for the next race there. That's how important the Daytona 500 is to a driver."

In a sense, Daytona shares a great deal with Major League Baseball. When the stock cars head to Daytona in mid-January for testing, it's like spring training. Speedweeks, the nearly two weeks of horsepower heaven for NASCAR junkies is like an abbreviated form of baseball's spring training game schedule.

And then there's the third Sunday of February, when the biggest, best and most popular race on the NASCAR schedule is held, signifying that it's batter up time for stock-car racing, with each driver going for the win, their version of a grand slam home run.

Even though the previous Winston Cup season just finished up less than three months earlier, everyone from the highest-paid drivers to the lowest-paid go-fers is ready, primed and prepared to begin the grueling 36-race battle towards the season championship all over again, and Daytona is the place where they get started.

"Daytona kind of sets the tone and pace for the year for a lot of teams," said Ricky Rudd, driver of the No. 28 Ford. "Everyone wants to do good and get off to a good start, because for a lot of teams, their season goes as Daytona goes. A bad finish at Daytona doesn't necessarily mean you'll wind up having a bad season overall, but you'd rather start out with a good win and momentum when you leave there."

While the world of Winston Cup racing is based around the Charlotte, N.C., area for most teams, Daytona becomes a home away from home for Cup teams for nearly a month from mid-January to mid-February. There's days of testing, countless driver appearances on behalf of sponsors, huge preseason and pre-race parties, Speedweeks and ultimately the biggest show of all.

In yet another sense, everything leading up to and including the Daytona 500 is a season until itself, where every driver, every owner, every crew member throws 100 percent of himself and herself into making just that one race as successful as possible. Forget the next 35 races; their attentions will focus on those events in due time. But until the final checkered flag waves, signaling the end of yet another Daytona 500, nothing else in the world of stock-car racing matters.

After all, this is Daytona. As Burton said, "There's nothing else like it anywhere in the world."
