If you've got a knack for trivia, try your hand at Commonwealth Edison's (ComEd) 'Coolest Summer Ever' sweepstakes and enter to win a number of prizes to make your summer a little more interesting.
During the 10-week contest that began Monday, participants can visit ComEd on Facebook and answer questions about Chicago and suburban destinations, energy conservation tips and other assorted trivia, according to a ComEd press release.
A different prize will be awarded each of the ten weeks.
They include a five-show theater package, White Sox scout seats and a chance to throw out the first pitch at a Cub's game.
A private tour of the Adler Planetarium's Doane Observatory and a limo ride to Rockford to see the symphony are among the selection of prizes that highlight civic and cultural institutions in the Chicagoland area, the release said.
Other slightly out of the ordinary prizes are a 'behind-the-scenes' encounter with a rhino at Lincoln Park Zoo and an in-water experience with a Beluga whale at the Shedd Aquarium.
The 'Coolest Summer Ever' sweepstakes runs through Sept. 2. For more information, visit ComEd's Facebook page.
