We are there pretty much every month and its a good show but a 5 hour drive may be too much. But here's an idea, if you want to see the Columbus show pm us and let us know and we can give you a couple ideas of some pretty cool stuff to do in the area as well as a couple really great little local restaurants that are definitely worth stopping at. That way you can make a pretty fun day of it. Also, if there is anything specific you are looking for I can make some phone calls and see if I can find it from one of the locals I know to be reputable and maybe up your odds of finding what you're looking for.
Hope this helps!
