Green Bay Botanical Garden lights up the holidays

The popular light show started in 1997 and has grown since then, evolving with technology.

There are old favorites like the caterpillar -- a popular spot for selfies and family photo ops -- and each year a new display is added.

This year, “Walking on a Dream” is new to the lineup. The interactive display has discs that light up and change colors when you walk on them.

“I went to a trade show -- a holiday Christmas light trade show, believe it or not; it’s huge! -- so that’s where I saw it. I loved it. I said, ‘We’ve got to have this,’” facilities and maintenance coordinator Dave Barkow said.

The WPS Garden of Lights is open Thursday through Sunday through Christmas, then only weekdays Dec. 26-Dec. 30.
