I went to this last year because my freind had tickets but couldn't use them, and it was suprisingly awesome. They put polar opposite people together and give them a controvercial topic to discuss. Its basically no holds barred. Arianna Huffington even got a pencil thrown right at her head by some heckler. Anyway tickets just went up for pre-sale, all you do is go to http://www.ticketmaster.com/promo/47seyc?camefrom=CFC_MSG_SPEAKERSERIES09. Choose the date you want to attend and on the next page near the top you will see an option for internet presale. Put in the code "DAILY" on the right hand side, choose your tickets; and you're all set! It's real easy.
A few of the notables: Bill Maher, Ann Coulter, Al Gore, Tucker Carlson, Paul Begala, Arianna Huffington, James Carville and Karl Rove.
Definitely a cool event, especially if you're into politics.
