Where's the best Dub?

Where's all the best dubstep at? I'm in Illinois and we have a lot of good local DJ's: Ana Sia, Rusko, Elliot Lip, and Alex B always seem to be killing it here. I just saw Ana Sia and Big Gigantic kill it two weeks ago at Tall Tree Lake Music Festival in Goreville, Illinois. I'm also going to go see Rusko break it down at the metro in Chicago this weekend, anyone else gonna be there?
