Repeat after me -- "bungee cords, bungee cords, bungee cords. . . . "
It used to be all you needed was WD 40 and duct tape. If it moved, and shouldn't, use duct tape. If it didn't move, and should, use WD 40. Then someone invented bungee cords. I can't get enough. You never know when you'll have to tie something on to something else; or tie something down, or tie something up; or tie one on; or . . . . . . They come in different colors! They come in different sizes! There are balltype and hook type, and . . . BIG ONES! and little ones! I know it's an addiction, but i can't help myself.
