Robin Harmon, who serves on the foundation's board of directors, came up with the Scoop-a-Palooza idea after attending a similar event out of state.
The goal, she said, was to do something that would benefit the community.
She said a steady stream of ice cream enthusiasts attended the three-hour event.
Jessica Patterson and her daughter, Katrina Snyder, 12, of Waynesboro, Pa., didn't let the heat keep them away from the cool event.
"It sounded like a fun afternoon event," she said. "It's so hot out and we love ice cream."
They planned to try as many flavors as they could. The pair already was on their sixth cup of the cold stuff. Patterson said she favored chocolate eclair, while Katrina gave the nod to strawberry shortcake.
"It's hard to decide," she said. "They are all so good."
Hilary Tadych said attending the event was the perfect way to beat the heat.
"It is so hot, I felt this was the ideal place to come," she said.
Tadych was on her fourth cup.
"This is probably all I can handle," she said as she spooned up some black forest. "It's wonderful."
"Yummy" was all Sherry Hoverter of Chambersburg could say as she peered into a freezer trying to make her selection.
"Decisions, decision," she said. "It's all very good."
Crystal Cosey of Chambersburg said the event was a great place to bring her family. She and her daughter, Taryn, 8, tried several flavors.
"We are always looking for stuff to do as a family," she said. "I am glad to see the Chamber (foundation) keep this kind of down-home activity."
Ice cream vendor Joe Miller of Trickling Springs Creamery said he was happy to donate his tasty wares for a good cause. His black raspberry won Best Flavor, which was voted on by those in attendance.
The vendors, including Brother's Pizza Ice Cream Zone, The Meadows Original Frozen Custard, Dodie's, TSC, Bruster's Real Ice Cream, and Goose Bros. and Trickling Springs Creamery, each scooped up about 12 to 16 gallons each for the event.
Harmon said she anticipated the event would raise $2,000 to $3,000.
"Next year will be even bigger and better," Harmon said. "Everyone seemed to have fun."
