Heard a legend that when USSR planned the manned Moon program, one of ideas for how to bring a humongous rocket to Baikonur was manufacture it in Moscow, then move by rivers to Caspian Sea and then move over land east, to the launch pads. For that purpose USSR started to construct a pretty big off-road vehicle - rather similar to what's pictured here, but dropped the project, as N-1 was decided to be built on Baikonur itself. Remnants of the vehicle surfaced somewhere on the Web...

Wonder if somebody could confirm or disprove this :) .
