Downtown Baton Rouge will be the place solar cars and backyard gardening meet during Louisiana Earth Day 2013 starting at noon Sunday.

“Every year I think, ‘we’re not going to top it next year,’” said Brenda Nixon, past president for Louisiana Earth Day. And yet, every year, there are new presenters, new educational booths and more people attending the event, she said.

Educational material and children’s activities will take place from noon to 5 p.m. along North Boulevard while live entertainment will perform on stages from noon to 8:30 p.m.

“Our Earth Day continues to be one of the largest in the nation,” Mayor-President Kip Holden said during a news conference Thursday.

This year B.R.A.S.S. will again offer the Bike Corral —valet parking for bicycles — to try to encourage more people to ride to the event.

New events include a recycled fashion show by St. Joseph’s Academy, an outdoor adventure game from the East Baton Rouge Parish Recreation and Park Commission and Pennington Biomedical Research Center healthy lifestyle activities.

Also new this year are a station for much younger children from ages 2 to 5, Nixon said, which fills a gap from previous Earth Day celebrations..

“We get a lot of families and they have kids of all ages,” Nixon said.

Also new this year is the Barn Hill Preserve from East Feliciana Parish with its baby kangaroo, Nixon said.

As a way to get people more familiar with Expedition BREC, the agency will sign people up for a six-months-long outdoor activity game where people register and then take their “passport” to different BREC sites.

BREC spokeswoman Cheryl Michelet said by the end of the game in October, individuals and families with the most points will be selected for a drawing of prizes, said Cheryl Michelet, BREC communications director.

“It’s a fun way to get people outdoors,” Michelet said. “And see everything BREC has to offer.”
