ok, i watch the History of the VW Bus tape last night, and yes, it does
have about 10 seconds of a syncro bus out in the desert. one shot of it
leaping over a sand dune, and another shot of it tearing down a 'road'
with the front wheels obviously churning away in the foot deep sand.

the whole seqment on the bus lasts about 7 minutes or so. even got the
eurovan on it. not a whole lot on the bread-loaf. :(

but! for those of you who haven't run across it, it's from
