The state Harley Owners Group, or "HOG" rally, kicked off Thursday at the Ardmore Convention Center. It will bring hundreds of riders and dollars to the city.
Last year, more than 1400 Harleys rolled through Ardmore streets, and the chamber is expecting even more than that this year.
The economic impact they have on the city in just the three days they're here is remarkable.
Riders fell in love with the Carter County scenery and could not pass it up this year.
The Harley owners from Oklahoma, Texas and neighboring states will gather at the convention center the next two days to talk about their passion, enjoy live entertainment and enjoy daily poker runs.
Chamber authorities say there's not an empty hotel room in town, and restaurants are packed.
Last year, it brought about a half million dollars to the city in just one weekend, and authorities are anticipating more this time around.
Only HOG members can attend the rally, but Saturday night, everyone's welcome to the HOG rally parade that starts at 5:30 at the convention center and goes through downtown.
