Farmers never fix anything right.

I'll give many of our farmers credit for being able to fix a lot of stuff "right enough to work," but it's D$@#%d sure they never leave notes for the next unsuspecting fixer. "Riskier" is probably an understatement.

I do have some documentation on obsolete US wiring methods, some going back to DC distributions, and some of that would make a smart squirrel reluctant to get in an attic. Fortunately(?) most houses wired with those methods burned down long ago, although I've seen remnants in a couple of abandoned sheds that collapsed for other reasons.
