Beat the worst of the summer heat while challenging your mind with a new puzzle! Participants can bring in puzzles they’ve completed to exchange with friends and neighbors. Puzzles can be brought into the Park District Headquarters during business hours June 17-18 and 20-21. Receive 1 puzzle for each puzzle you bring in. Doors will open at 10:00 am sharp on Saturday, June 22 for participants to pick out some new ones!
