CHICAGO — It may not feel like summer just yet, but don’t let that fool you.

The party was switched on today with the help of WGN’s very own Tom Skilling, as he helped signal the start of summer by turning on the Buckingham Fountain in Grant Park Saturday.

ComEd and the Chicago Park District joined Skilling in celebrating the start of summer with a free event Saturday afternoon.

“Every year when we turn on this fountain,” said Rosa Escareno, general superintendent and CEO of the Chicago Park District. “It means a celebration of families and kids and individuals enjoying summer all year.”

While today’s celebration lasted until 3 p.m., the Buckingham Fountain will remain running from now until mid-October, weather permitting.
