I was born and raised in Yuma, AZ and remember very fondly the filming of ROTJ back in '82. It was the worst kept secret in the world as the locals had been told that there was a horror movie being shot. All you had to do was stand on the corner of 24th Street and 4th Ave. in Yuma and watch Carrie Fisher get out of one limo and Mark Hamill and Harrison Ford get out of another at the front of the Stardust Hotel.
For anyone that is interested, I know VERY well the area where that barge scenes were shot as that was my playground growing up in Yuma. I have personally scavenged pieces of the set for my own personal SW collection. I do not currently live in Yuma, but I go back often because my family still lives there. If anyone is interested, the next time I go, I can make an announcement and take anyone who wants to see the remainder of the set out there to see it. It is between Glamis and Buttercup Valley and not far from the area that the final battle scene from the movie Stargate was filmed. I have some really fond memories of riding sand rails out to the set and watch with binoculars the production of a phenomenal movie!
If you are interested, please feel free to contact me! My name is Corky Cobon and I would love to pass on my knowledge of ROTJ being shot in my home town!
