(April 10) BOSTON — It was back to the 1970s, but in a newer and bigger venue for the New England Produce Council’s sixth produce and floral exposition.

The “That Produce Show” theme — a play on the popular “That 70s Show” television series — had some exhibitors dressed in ’70s-era clothing and decorating their booths with memorabilia from that decade for the April 5 show at Boston's Convention and Exhibition Center.

The theme may have helped keep attendance high. Show sponsors estimated 750 to 1,000 attendees and exhibitors, higher than last year’s nearly 500.

The show featured 220 booths — also up from last year’s 186.

An exhibitor thank-you reception that took place April 4 in the Omni Parker House rooftop ballroom was packed with up to 400 participants, said Laura Sullivan, the show’s executive director.

Paul Kneeland, council vice president and director of produce and floral for Wellesley Hills-based Roche Bros. Supermarkets, said for five years the group has wanted to move to the center that offered a smoother flow for show participants.

The 1970s theme, Kneeland said, made the show fun for participants who walked the aisles in a facility that was larger than where last year’s show took place, the Hynes Convention Center in Boston.

“This show has been spectacular,” he said. “It’s all we could ever hope for.”

Council secretary-treasurer and saleswoman for Vero Beach, Fla.-based Seald Sweet International, Linda Cunningham, said it was good to see more exhibitors at the show.

“It’s exciting to move here to the convention center. It’s like the big time,” she said. “When we started six years ago, we didn’t even have carpet.”
