Several hundred people visited the Hinsdale and Oak Brook police departments' National Night Out earlier this month in Oak Brook. From a K9 demonstration to pie eating and pie tasting, there were plenty of activities for visitors to enjoy at the event. Hinsdale police officer Grant McElroy and Sgt. Mark Wodka were no match for the Oak Brook Public Works department's pie eating team.

Sawyer Meyer was able to create some very large bubbles. (Jim Slonoff photos)
