The NASCAR Bojangles Southern 500 race in Darlington this weekend is expected to bring in about $30 million to the local economy.
The Darlington Chamber of Commerce expects more than 75,000 fans to make their way to the track.
"It's obviously our biggest week of the the year as far as population goes. That's a lot of influx. Darlington Raceway has put us on the map," said Danny Dubose with Darlington Chamber of Commerce.
Officials say hotels and motels in the city are already sold out.
Fast Track gas station is right around the corner from the track and has been busy the past few days as traffic rolls into the area.
"Pretty crazy. It's really a busy weekend. Very busy.They come in and they eat with us and we recognize them by face a lot of them. It's just a good weekend all around for all of us, " said Bonnie Galloway, Fast Track Manager.
The store is taking full advantage of the weekend.
The manager says they're also making money from vendors who've paid to camp out in the parking lot.
Other businesses in town have special deals to lure in race fans.
Some stores that are normally closed on Sundays will open this Sunday in effort to make an extra dollar or two from race fans.
Chamber officials say the race is vital to the Pee Dee economy.
