I only managed to unload two of the first six pairs I bought. The wife's skis became part of my quiver when she quit skiing. The kids contributed several pairs of garage sale sticks to the quiver, but I was able to eventually unload most of them. I now have a bunch of redundant retro sticks, a sizable "rock ski quiver".
I don't know who would want to buy them and sooner or later the local scout troop will come by looking for a donation to help them build a new sled for the Klondike Derby. I'm not crazy about that idea or letting someone turn them into a fence or chair.
Sooner or later I'll have to find a good home for the excess or the wife will toss them out. The scary part about that is she won't know which ones are the excess and which ones are the usable ones.
Apart from nostalgia, or "retro days", there's not much demand.
It's amazing that some folks still actually ski them. Gotta admire their "keepin' it real" attitude.
