The Manassas show is right in my backyard, so I've been several times. It is not very big, and I've heard the Richmond show is even smaller. I would not drive 5 hours to go to the Manassas show. If you ever decide you want to go on a bit of a road trip to a show, I think you'd probably be happier driving twice as far to go to White Plains or Hamburg, which are supposed to be great shows.

Have you looked at Repticon's website? They have a lot of shows in the southeast, and are branching out a bit, so maybe they have some stuff closer to you.
