The music, provided by Blackjack Sound and Light, set the mood with old rock and roll,for the city's first Cruise In, hosted by one of Mammoth Spring's newest businesses -- Mountain Man Iron Works, in operation less than a year.
The store, which makes and sells decorative yard and household metal pieces, is located just up the street from where the car show was held.
Employee Evan Schultz said the show was a gesture of thanks toward the community for patronizing the new store.
"I'm in utter amazement," Schultz said of the turnout of car enthusiasts, many who still were driving in with cars to show a half hour after the three-hour event began.
"This is what I mean about the community supporting a town."
Schultz said the store has done so well that the owners are able to think about future expansion.
Admission to the car show was free, for those who brought the polished muscle cars, hearses, motorcycles, trucks and tractors, as well as for spectators.
The only money generated was from food and raffle ticket sales.
Mayor Jean Pace was busy at the hot dog stand, selling food and greeting visitors, as motorists cruised by at 5 mph.
"We're very pleased," Pace said, of the number of cars in Simmons Bank parking lot and along the street. "For a hot August night, this is wonderful."
The raffle included many prizes, with the grand prize being two metal model cars from Mountain Man Iron Works.
All proceeds went to the local Shop with a Cop program and the Mammoth Spring food pantry.
