Win a $20,000 Diamond Ring! The 2nd Annual Annapolis Diamond Dash

This is a real treasure hunt we're talking about... with a $20,000 Martin Flyer diamond ring as the pirate's booty. On September 17, the 2nd Annual Annapolis Diamond Dash will take place all over the city's historic downtown. And did we mention it's free to enter this one-day treasure hunt? All locations and challenges will be delivered straight to participants' cell phones. It's easy: Grab a teammate, solve riddles, and earn points! Teams of two answer riddles and complete challenges right from their cell phones, as they follow clues throughout the downtown area for the chance to win the ring. What's more, participants are also granted access to the exclusive after-party, hosted by Loews Hotel starting at 2 pm. For more details, check out the website.
