The problem lies with those who think of "spring" as a season. Wht it is, is a device, usually of metal, in the form of either a leaf, as in a leaf spring which is a flat piece of metal bent into a V or W shape, not a leaf on a tree, or a coil. Used to either return something to a position or retract it from a position. Often used in fly reels in one form or another.

Spring as a season has been highly overrated in 2013.
