I had heard the rumor that they might move them and couldnt find anything until I checked out the "visit Ohio" website and they have them listed as being held down by Columbus again and the dates are 8-7-09 thru 8-9-09.
The nats is a great show! If you go the the web site www.moparnats.org you can get a phone number to call. It gives the 2009 dates on the recording. I called after hours and got the recording , but the dates are on his recording.
