The last Ice house storage unit( from the old days) I am aware of went up in smoke about 3 years ago. Heck of a bonfire. Before I moved my shop some 17 years ago I had about a dozen huge Harvester chains hanging on the wall, about 8ft loops, these were used out on Lake Michigan to cut large blocks of ice. Up until about 5 years ago I was still making specialty bars and loops for a firm here in town for a a machine that would cut 50#blocks down to 1/2 and 1/4's, Those went to the places for various shaved Ice drinks,snow cones and such.
