for me, places to hang stuff at camp are never in great enough supply, especially in moist weather, when you can't just drape things on your drying lines.
but you want to hang your headlamps where you can find them, ya? and your rain jacket? and your map bag? and a bazillionty other things you don't want to leave on the ground and you have limited table space?
yeah, you need hooks.
well, my friends. you tie a lark's head in a bungee cord on your ridgeline and you have hooks. slidey enough to reposition, but grippy enough to stay where you want them.
