Good morning from a "newbie" in Iowa

I'm thinking about making the drive down to the show and I've looked at the flyer and photos here.

Is this a big show with numerous parts for sale/swap?
Will there be dealer displays?
How many people normally attend?

So sorry for the questions, but before making the drive I was just curious about what to expect.

Won't be driving my '48 Chev 1/2 down yet, I'm in the process of a major restoration and the worst part maybe remembering where everything belongs once I get to the reconstruction/assembly process.

Thank you
Jeff
