The 2004 International Model & Hobby Expo will be October 14-17, 2004 at the Convention Center in Rosemont, IL, USA.
The 2004 Hobby Visions show is in Las Vegas on the same dates (so one of these two shows will likely be pretty low-key...)
The 2004 RCX show is April 23-25, 2004 at the Anaheim Convention Center in Anaheim, CA.
Hope that helps.
