One near me built in 1890.I was up in the attic of a house my son just rented here in California.
Knob and tube!?!?!? None of it I could see was still live, but couldn't see all of it.
Grew up around it, replaced a TON of it in my years....but NEVER seen in in CA. Just not that many old houses.


I know there are old homes in Cal. Not many once you get away from the coast & main cities. Thats all. Much rarer in the central valley....
