my question is, if it was intombed, how did all that mud get in there? wasent there like a concrete top to it, what did they use 2X4's and a tarp and said see ya in 50 years? i mean that thing should of looked like the Delorean in back to the Future 3 when Marty finds it in the cave with only a tarp on
j/k but I just cant figure out how so much mud got on it really.
