Grete,
I totally understand where you're coming from. Last season I hit up a bunch of big air and pipe competitions, but very few have had girls divisions. Sometimes they let you compete with the guys and sometimes you get to forerun and that's awesome. Sometimes you get told that 'the jump is too dangerous for girls' and that's where the bullshit begins. But the best you can do it get out there go in as many competitions as you can and show them that girls can rip. Sometimes just asking to hit the jump a few times in practice is enough to prove that you can safely compete with the boys and then you get your chance. Don't get discouraged, because it's frustrating, but don't worry, it'll get better.
Good luck and keep on representing for the women.
