Morgan also ate some funnel cake and later that afternoon was enjoying a blueberry shaved ice, she said.
"For me, the best part is just being outside," Stahley said. "It's a nice day to enjoy listening to music."
Four bands performed in the bandshell Sunday: Blue Rhythm Boys, David Bach Consort, The Carl Filipiak Group, and Rosie Ledet and The Zydeco Playboys.

"The bands are better this year," he said.
Elizabeth Russ of Hagerstown said she works for the city and is a patron of most city events.
"I come out here ever year for (Blues Fest)," she said. "I just enjoy the blues."

"We always come together," Jackson said. "It's been nice."
The two said they were enjoying the food and the chance to relax outside.
"It's nice that everybody comes together, no matter what creed or color, and has a good time," Jackson said.
The Washington County Museum of Fine Arts also hosted events Sunday.
"We'll be back next year," Rizzo said. "I think it just gets bigger and better every year."
