GREAT idea!!!
I'm going to build a small shed to park Mrs. Augie's collection of lawn mowing machinery. I think using the old planking to veneer the exterior will give it a nice look.
It is a filthy job taking it down but the end result should make the effort worthwhile. I hauled two loads home over the weekend and we've got the slats removed on another 12' section so that will come off pretty quickly. Probably get that little bit done this evening.
