If someone can get some cars or vehicles, I can rust them up and make them all damaged as if they had been there for a while.  As for the copter, I believe I can make it.  It shouldn't be too hard.

Oh.  And you would need skeletons.  Not many, just enough to make it obvious that no one was there for a long time.

In order to go forward, one must often times look to the past.
