Fans enjoy opening day at the Speedway

Saturday marked "Opening Day" at the Indianapolis Motor Speedway.

With the waving of the green flag, the Indianapolis Motor Speedway is officially open.

The cars took their first practice runs as fans got their first looks at their favorite drivers Saturday. It was a classic clash of old versus new in the starting lineup of events.

The energy is so high for opening day at the Indianapolis Motor Speedway, it's contagious.

Pagoda Plaza filled up early Saturday morning, not with the fast cars IndyCar fans come to see race, but with the slower variety any car enthusiast comes to love at the Celebration of Automobiles.

Margaret Dunning is 103 years old, but Friday she got to drive her 1940 Packard Roadster around the famous track.

"Very exhilarating, especially on the first turn into the old bricks. It was as exciting as I expected to be. It had its ups and downs and sways," said Dunning.

But for fans Saturday, it was all about the highs. They were on cloud nine meeting their favorite drivers. Sean Majeske is only ten years old, but he knows the art of racking up the autographs.

"I got Scott (Dixon), Mario (Andretti), Dario (Franchitti)," said Sean.

"Are your friends going to be jealous?" asked Eyewitness News Reporter Carrie Cline

"They will be," said Sean.

With the ceremonial passing of the keys, the official pace car took to the track.

Not long after that, Mayor Greg Ballard waved the green flag and the drivers took their first practice laps.

Steve Thompson has been coming to the track since 1969. He's brought his son Alex, now 21, since he was 8.

"I'd rather be here than almost any other place in the month of May," Thompson said.

"Every since I was a little kid, my parents said I could come to the track and say and do and drink whatever I want," Alex said.

"We condone eating as much as they want to, eat and drinking as much soda pop as they want to drink. That kind of thing," said Steve.

And when you're not checking out the action, you can check into the Social Media Garage, where you can log into your Facebook or Twitter pages and see what your favorite drivers are up to - many of whom are posting behind the scenes looks.

"They're fans of you, they're interested in your career. They're investing time in you as a driver. You gotta give them some info back," said driver Josef Newgarden.

Opening day activities wrap up at 6:30 p.m.
