Black Phantom, stop being a fat troll and stfu.
For everyone else thanks for the help, although your critiques (especially catskills and abubob) are really not relevant.
Abubob-I'm trying to come up with a ski brake solution, not trying to warn people of out of control skiers, so I have know idea where you're going with your idea.
Catskills-it's not a bad survey just because you can't remember anything. I've talked face-to-face with ski patrols who have identified 15-45 as a reasonable age group. I'd appreciate if you'd say something scholarly next time rather than bashing my survey because of your personal problems.
I was just confused b/c of the other HS kid posting here too, with almost the identical query and the same fairly simple 3-question poll.
Good luck with your project!
