Is this the place you are thinking about...
Aerial Visuals - Location Dossier - Oklahoma Museum of Flying - Doc Hisey Private Collection - AD, L-39, P-51 ...if so follow the link into the location dossier. At one point someone sent me some hours information, and I have it posted there. I can't say if it is current.
If you do visit... take pictures! It would be great to have a few uploaded to the airframe dossiers.
