I went to the filming areas you can get to for my birthday trip last year.  It’s i think like a 2 hour trip outside of San Fran.  (I live in Reno) all the speeder bike chase sites and Princess Leia’s meet up with wicket and the two scout troopers are still there.  But the entire battle of Endor where they placed the Shield Bunker is gone.  It’s an awesome sight though.  Just don’t get your drone stuck in one of the trees like I did.
