Here is my view on it.

I voted to leave it in Muncie. In my world, I much prefer having a known location each year that I have to go to. Having the Nats in the same spot each year makes the trip so much easier, I know the hotels, I know where to eat, I know exactly how to get there, how much time to take from work, where to practice etc. etc. etc. That at least makes the long drive somewhat palatable.

To have it in an unknown location may not make it as easy to attend, even if it was closer distance wise.

We don't have a facility like Muncie in Canada, and we basically don't have a Nats because you can't find anyone to hold a standalone one. To me it just seems like such a waste to not use a facility like Muncie!
