CONCORD, N.C. -- Tuesday afternoon, a very special guest visited the Hendrick Motorsports campus.
And he was in for a big day.
Mark Zuckerberg, the founder and CEO of Facebook, laid out a personal challenge for 2017 "to have visited and met people in every state" by the end of the year.
His trip to North Carolina featured a glimpse into NASCAR courtesy of Hendrick Motorsports.
"The reason why we're here is I've been going around on our year of travel, going around to each of the different states in the country and trying to learn more about community," Zuckerberg explained during his Facebook Live. "NASCAR and driving -- sports in general form the basis for a lot of communities."
To kick off his experience, he took a tour of the organization's Concord, North Carolina, campus led by general manager Doug Duchardt and No. 48 team crew chief Chad Knaus.
Then he headed to Charlotte Motor Speedway for even more action, including some hot laps around the track with Dale Earnhardt Jr.
“It was fun to go out there for a few laps with Mark and to give him an idea of what you feel when you’re in a race car,” Earnhardt said. “We definitely got up to a pretty good speed there.”
Take a look at some highlights of the day -- including Zuckerberg's Facebook Live of his at-track experience -- below.
