This reminds me of my previous house in Cleveland. In the basement all of the plumbing and electrical wires had tags hanging from them with nice clear labels where it was from and where it was going, very helpfull. The only thing that was bothersom was the tags were for explosives. The original owner was a treasurer for the Austin Powder Co. So seeing a tag for dynamite that says (hot to kitchen from heater) is a shock at first.
Bread clips will not cause any one in the future to almost call the police the first time they see them.
