Where are you?
upper midwest... minneapolis to be specific, but I am not opposed to travel (especially this time of year)
In my personal opinion, the best conference coming up is Post|Production World conference, in Las Vegas. It starts before the NAB show and extends into the middle of the NAB show. It's at the same convention center complex, too. There's a _lot_ of great material at this conference for After Effects. Chris & Trish Meyer and Richard Harrington are usually there.
I'm presenting this year, too.
There was also a conference last year, Motion '09, that people seemed to like. That was in New Mexico, I think.
thank you, kind sir. Hope to see you in Vegas.
