I am wondering how the Lunar Rovers got enough traction to operated on the moons loose surface with only 1/6th the gravity of Earth.

I have known Bill since I was 19 years old - back in the dark ages. I was a student when Bill was training the Apollo astronauts to do geologic sampling during their moon landings. He remains one of the most brilliant people I know and, MOST importantly, one of the most principled person I have ever met. He would never have participated in a hoax.
As to the subject of this thread. If you listen to the astronaut's transmission form the moon,it is obvious that most, if not all, of the concerns discussed by the first poster are discussed by the astronauts in the clip - if you have it with audio - see this link http://video.google.com/videoplay?docid=1502962445208997168 (The audio only is edited for television broadcast, eliminating the 8 second gap between earth and the moon.)....Two of the most telling remarks made in the audio of the first ever moon rover mission, The Google video clip above, are "Is he on the ground at all?" and "when he turns, the back end breaks loose just like on snow." It wasn't easy driving on the moon.
What was different between training and actual EVA? The Earth trainer had rubber tires and could support its own weight in 1 g. The flight article would have collapsed in 1 g if the crew sat on it. Since the handling characteristics of the LRV could not be fully tested on Earth, a "grand prix" test was performed by the CDR on A-15 & 16. The trainer provided adequate simulation, the major difference was the necessity to pay constant attention to the lunar terrain in order to have adequate warning of obstacles, especially in adverse lighting situations. Braking required ~2 x the 1 g distance. Steering was not as responsive between 8 - 10 kph with hard-over inputs.http://ares.jsc.nasa.gov/HumanExplore/Exploration/EXLibrary/docs/ApolloCat/Part1/LRV.htm
, this is an interesting and hotly debated topic it seems. I have a question which may seem silly but when watching the real time videos of the moon buggy in action, why does the dirt sent up behind the buggy by the rotation of the wheels return to the surface so quickly, I would have thought that the dust particles should remain airborne for a longer time frame? or am I missing something her as well? I am not a conspiracy theorist at all but found this interesting.
