I'm not clear how big your group currently is, and whether you're considering adding one newbie or two. Are you confident that your group will be able to make and abide by decisions when necessary? (e.g., do we turn back now?)
Have these people ever been camping in the winter? At least been skiing? Know how to recognize and treat frostbite or hypothermia?
Everybody has a first time, but a winter Presi Traverse probably shouldn't be it. If you've never put up a tent before, you dont' want to be figuring it out in a whiteout during hurricane-force gusts.
