R2D2 was an iconic Astromech droid from the famous series Star Wars, and was one of the few characters to appear in all films. This Geocache is not dedicated to this famous little droid and counterpart to C3P0. It is said that during the movie American Graffiti Sound Editor Murch asked for Reel 2, Dialog Track 2, in the abbreviated form "R-2-D-2". Lucas was working on his Star Wars script, woke up, said "Good name" and went back to sleep.
