Wel yes, Pinal Airpark is nice. The NASA 747 is usually parked there. And if you take pictures, there's a whole lot of security cars patrolling the tarmac, so take care when you do that. But it's not a site for warbirds.. .For that you better go to the boneyard in Tuscon. Buy a ticket at Pima Air & Space museum and enjoy, as the guys here already wrote here.
Have fun,
