It’s time for a city smackdown! As part of our Destination USA project, we’re pitting rival cities against each other. This time, it's the battle of the underdogs: Philadelphia, Pennsylvania, vs. Detroit, Michigan. If you love Philly, here’s your chance to stand up for the City of Brotherly Love! Tell us the very best thing about it, or the one or two reasons you like it better than any other. Make sure to include your most stunning Philadelphia photos to back up your claim. Show us why you can take on Detroit any day! The best stories, photos and travel tips could be featured in a CNN story. This assignment is now closed. Which city won? Find out on CNN.
