They asked us why we were there and what we thought it was.
They had only started filming the day before and the barge was buttoned up most of the time. But R2 was up on the deck.
I pointed up at him and said. "Well, I'm pretty sure it's Revenge of the Jedi or R2 is on vacation."
We asked if it was cool to hang out and they said it was fine. I even asked permission to pitch a tent at a later time. They were cool with it all as long as we did what they asked, sure....... Not a problem.
I spent 2 weekends and a 6 day (2 of that sandstorms) campout total time.
They actually kept in touch with us for about a year and half after that, through the release, asking us how we thought it was all going.
And as cool as that was. What came later was even cooler.
I'd be impressed if someone can find that story. I am pretty sure it was published in a Bantha Tracks. I and some of the others "involved" did an interview.
