- vagabond
I guess we DID!
I remember that the area was next to the museum and we weren't sure if we were supposed to be out there or not. That's why we don't have full walk-arounds of the AFVs - we were kinda hurrying!
First rule of AFV spotting in questionable areas: Look friendly, innocent and confused (the last two are easy for me) and act like you're supposed to be there until someone challenges you. Then get that "I didn't know!" look on your face and point at the old stuff pleadingly.
I managed to get into some restoration areas at a few places when ropes were down to facilitate staff movements...and never knew I wasn't supposed to be there until they put them up again after I wandered out once I got my pictures. I'm sure I was being watched the whole time, but keeping your hands in your pockets when not taking pictures can go a long way.
