I'm pretty sure the tryouts for ANW 2011 are in California like the previous tryouts. Most likely in Los Angeles, California. Also the previous tryouts were in August so that is when they will probably have them. To find out exact details one will have to constantly check on the G4 AMW page for updates when they decide to put up the time and date.
One can show up and wait in line for the tryouts or you submit a video and are selected to be a competitor. Either way you have to pay for yourself. Make sure you are well prepared to make it because if one pays all that money just to fail it would be a disappointment.
