For the Harrison family, auctioning is in its blood.
"My granddad and dad were both auctioneers," said John Harrison of Harrison Auction Center.
Harrison's son also participates as an auctioneer, and his grandson will be one soon.
Harrison said he tries to tell potential buyers as much as he can about each mule.
"Missy is broke to ride, but she needs an experienced rider," Harrison said as he was auctioning the mule.
Harrison has been auctioning off mules at the Fulton Street Fair for years.
"You get to meet so many people," he said.
Harrison's employee Hershel Linneneringer also came to Friday afternoon's auction during the Fulton Street Fair. Like Harrison, Linneneringer relates information about the mules he's selling.
"He wants to try to please. He's easy to handle," Linneneringer said about Lightning, a 35-year-old gelding.
Two mules, Moonshine and Sundance, valued at $4,500 each, didn't sell. Linneneringer said he's been to auctions where buyers will spend more than $20,000 for a mule.
Merv Willoughby, of Columbus, Georgia, came to the auction with his in-laws, Lou and Betty Lewis, of Fulton. He said he's owned cows and chickens but has never owned a mule.
"I grew up on a farm and like this kind of stuff," he said.
