I'm going to go with maps, I have a hiking boot box literally full of trails illustrated and other various maps. Hiking boot boxes work great, they are a little deeper than the folded up TI maps are wide and you line them on their sides really well. I also have 4 full sized quad maps mounted on my wall (Mt Jackson, Vail East, Mt Powell and Willow Lakes). I want to get the Storm King Quad and post it too.
Second would be skis, I think I have 7 pairs now. Not as much as some other skiers I know, but I did toss 2 pairs rock skis that had broken bindings after last season.
