From my own understanding from my friends who work for Gen Con, LFL chose LA just for now because of what happened at C3. The Indy Convention Center was to small. And they told ICC that it was and that in order to get them back and many conventions that we lost the past couple years was to expand the Convention center which they are working on. But as I said before if you have one in Indy it can not be before 2010, so they have time to finish the Convention Center. On the note of walkies, I don't know why they didn't use them in LA but I know when Gen Con runs their main event every year they do have radio communication. Watched a guy get tackled for knocking Con-goers over one year.
