Thanks... I was always under the assumption that Iowa Gas was larger than Dixie Gas... ooh well 😉😆 .. maybe two trips needed
They are two different style shows. Both cool in their own way. Columbus CTO is very cool too. Iowa and Columbus is a hotel venue with a parking lot full of cool stuff and room to room vending, which is always fun. Dixie gas is over 500 vendors (all petroliana) spread over several acres.
I can tell you, if you’ve never been to the US, the Smokey Mountains and the area around Dixie Gas is very scenic with the National park there too.
No matter what you choose, you’ll have a blast.
