Replying to Research Project about Neschool Skiing

Hey Dudes!
I was wondering if any of you have any data on how freeskiing has affected various ski resorts?
How much money are resorts putting into terrain parks? How many percent of todays skiers own twintips? How many regularly go to parks?

You guys know what kind of questions I mean? Has there been a survey anyone knows about?

I'd be happy about any information, because I don't wan to do a lame ass project on something stupid.

Thanks in advance...

Felix
