You and your classmate Brad both posted weird surveys on things nominally related to skiing.
I commend your enthusiasm and desire to apply your creativity to finding/solving problems in the ski arena. But as a skier, both surveys appear to ask questions that are either ridiculous, or don't allow for answers that are realistic.
Have we dropped something from a lift? I'd be surprised to find anyone who has skied for more than a few years to answer no to that question. But what's your point/goal? I've dropped or seen people drop gloves, poles (two most common things), skis cigarettes, joints, roaches, lighters, phones, hats, goggles, tissue, candy, puke, even small children.
If your goal is to design a leash system, you might want to design your question more around people dropping the kinds of things they might leash (e.g. gloves). If you're aiming to design a catch net to hang below chairlifts...well, good luck with that. If you want to sell them insurance for dropped crap...???
Now, if you want to design something kind of cool, how about a little basket that clamps onto the safety bar? Give us a place to put our gloves while we answer our phones. Heck, you could even leave room for replaceable advertising so the ski area gets these little things for free (some firms already do this with trail maps on the safety bar). If you start with some sort of concept like that, I suspect you could ask a bunch of questions that would get you much more valuable data.
I'm liking my idea of a little basket advertising thing more and more.
