"It's a delightful day to spend strolling," Costello said, adding that she and Derwart planned to visit the stalls in the Wine Bin's parking lot, as well. "But I have to confess – I'm usually driving through."

Columbia resident Yelena Betz, said she liked the "openness" and the "relaxed" vibe. When compared with the Columbia farmers markets, she said, "I like this market better because there are more vendors."

Vendors said their sales were generally strong.

"So far it's been good," said Colleen Histon, who owns Shepherds Manor Creamery and makes cheese and soaps of sheep's milk. "It's surprising to me, actually; it's better than I expected."

Jeff Torres, who was selling Cliff's Salsa in the Wine Bin's parking lot, said he's participated in a lot of markets. While it's still a bit early to tell how this one will pan out, he said, "I like the traffic so far."

Jim Grinder Sr., who was manning the booth at meat vendor Orchard Breeze, said that while the first three weeks were busy, "this week there's not as much" traffic.

While the market is still in its early stages, Kepnes said she'd like to see it "grow as much as [it] can." She envisions partnering with other Main Street businesses to encourage sidewalk sales, a flea market and guest chefs.

Last week, she got some encouragement from State Comptroller Peter Franchot, who came to visit her business and learn about the market.

"People appreciate places where they can come together," Franchot said afterward.

He likened it to 19th-century markets that united community members on their weekend shopping excursions.

"This is a throwback," Franchot said. "In the 19th century, places like this were the center of the community, they were pulsing."

And, he added, "I'm here to say this is the future."
