LOL! The Shed... back in the late 60's early 70's was always crowded; but we were always hungry...
as for running DH, there was never 'netting' on any courses back then, an occasional 'gate' (bamboo pole) to direct racers and you were grateful/lucky when the course wasn't through moguls or water bars which weren't filled in... course maintenance really didn;t exist much... spectators were like squirrlels...
I do remember one course at Elk in Pa, where, to get a long enough course, it down one mogul pitch, hung a hard turn onto a cattrack to another mogul pitch and then another hard turn onto another cattrack which took you back to the 1st pitch. Thing was, if you didn;t keep up your speed through that last mogul pitch you then hit the flat run-out and barely made it to the finish (or so it felt...)
An off-course trip into the woods was not a rare occurrence back in those days. I had the lucky experience back in the NY State DH at Gore. Life-Changing...
that film may have been '78, but that DH sequence had to be from early 70's, 72-73-ish.
The freestyle stuff was more mid 70's stuff, especially considering the short skis, outfits, 'staches and poms... LOL! very groovy! but not my thing...
squadra corse not Mk IVs, Banshees not Hanson or Scotts, M4 & rotomat FDs not spademans
