They're in my second bedroom closet, each in its own cover, resting against the wall.
Same drill for me. I don't do any prep work/waxing, I just make sure they're dry.
I've heard that skis may lose some of their camber(?) if they're not stored hanging from pegs. Any gear geeks want to comment on that, or is it another myth busted by the Myth Busters?
I probably should prepare a bit better wrt ski storage, but frankly, it's down there on my list of priorities.
