I solved this a few weeks ago, with the help of a biker friend. As I was lying in the hospital recouping, I had the chance to watch all of these movies twice. Thanks for the flowers by the way.
As we were retrieving the cache, the local constabulary pulled up and was a little curious as to what we were doing. But fortunately I had also just watched the original Star Wars while I was convalescing and I learned a few tricks. As he pulled his cruiser nearer, I waved my GPSr at him and said, "We aren't the droids you're looking for." and he went on his way. May the Schwartz be with you!
