Look up Tee Time, Flying Circus at least. A more modern collaboration with a few others would be Teddybear Crisis, in the Top 3 Best Action Sports Movies ever.

It shouldn't matter that fewer women have been in action sports as a whole for a long time, many women just haven't been pushing themselves on the same level as guys from Day One as there hasn't been much competition - not the fault of any jumps or their sizes.
Looking at the Nine Queens just now, the jump was TOO SMALL for the girls! The tricks thrown this year were plentiful, quite stylish and there were a lot more unknowns that had amazing tricks, but the size of that jump seemed limiting to them, really. It would be fun to see which pros pictured this idea.
Also, remember than in the survey that Leskinen did, it was for both skiers and snowboarders if I recall correctly, with that one chick from Amped who isn't even doing comps anymore weighing in here opinion, wanting to separate not only women and men's courses but also skiers and boarders...
