How interesting. At first, I thought this idea wouldn't work, but it ended up being a huge success. My team at The List (thelistamerica.com) and I got in contact with students from Harvard, MIT and Wellesley to throw a "secret party" at an undisclosed location (it was Emerald). We required a code to get a ticket and find the location. We gave the code to 10 people and just let them roll with it for 5 days...
200 people showed up.
Right!?!?
