BROOKFIELD, Ill. — Hundreds of people pitched in Sunday to get Brookfield Zoo all dressed up for the holidays. 

The crowd’s mission was to tree trim and decorate more than 650 trees.

The zoo starts selling them to families and groups in September and they’re usually sold out within a month.

Brookfield Zoo’s Holiday Magic

Leah Rippe is the zoo’s vice president of marketing and communications.

“We supply the tree. We supply the lights,” she said. “They come in and trim it themselves.” 

Many tree trimmers brought handmade ornaments with special meaning. 

Rippe says the annual tradition helps to beautify the landscape ahead of the Holiday Magic celebration at the zoo. 

“Starting the day after Thanksgiving, we have over two million lights illuminated for guests to come and walk through the park,” she said.
