The pictures show the various signs to Base Camp for the "E7" production, which is just the name being used for Transformers 2. If you look at picture 4, a little right center you can see the Chevy Beat that was first spotted at The Udvar-Hazy Center over the weekend.
At the 78 acre sized cemetery you can see that lighting and filming rigging is being set up. There is also a large truck that might be a generator truck. In addition the Chinese camera copter used for the Bethlehem shoot makes an appearance. From a source the difference between the copters used at the Bethlehem is the camera copter is a BA with a small rear window while the A-Star has a large rear window. I guess after this shoot the copter will get returned to its not Chinese labeled state.
The video is footage that John Von shot of the copter flying around. I have no idea what its doing though. Maybe filming, maybe practicing to get the lay of the land.
Thank you to John Von for letting me use his pictures and video.
