Yeah, I have to say, that was kind of my reaction too; the look and description of this top-level - but 40 year-old - footage makes me think less about fun than about traction and plaster... I mean, fun to watch somebody else do it, sure; big, long tracks with big, long corners, ridden with big, fast bikes is an amusing passtime for guys with names like Dick Mann (the most macho name ever?), but it seems a stretch from my current armchair.
