Google Maps can really be your friend.  I was hoping to find the time to get to see the space shuttle stack in Expo Park while I was back in LA if possible.  I went on Google Maps to see how to get there and the layout of the area and I saw a tag for an A-12.  Sure enough, the twin seat Lockheed A-12 is mounted on display right next to the parking lot.  It is tucked in between the lot and a pathway over a dip in the grounds.  It is rather tight to the parking lot which made getting shots a touch tricky but the early morning light when I was there was the best angle for it.  I was pleased to add an unusual airframe to the briefest of visits!
