Oh man, I hate demo. Haven't done much of it really but everyone seem to like it to get their frustrations out. An old friend asked if she can be involve in the next demo because of her divorce. Sure, why not

. I gave her a pair of gloves, googles, mask, a big hammer and a shovel. She lasted about 30 mins and I took her to breakfast instead. Never asked again.
Glad you were able to expose that J-box and knob and tube. There are lots of creative work buried in old duplex and other rental type buildings because most owners are cheap, seem to hire handy-man-deluxe to perform work that's a bit over their head and don't understand or know building codes.
