 If you're looking to stay cool today, a big event in D.C.'s Capitol Hill area could get you some free food and a spot in the Guinness Book of World Records. Barracks Row Main Street is looking for volunteers to help build the largest ever human image of an ice cream cone. This is set to take place around 11 this morning, right after the Independence Day parade. Approximately 900 people are needed to do this. All participants will get a free scoop of ice cream after the event. WTOP will have a reporter there as well.
