11 years ago, when we built this new house, they wired all the
low-voltage wiring and dry-walled on the same day, while I was out of
town :-(

My original intent was to photograph each installation.

Though there was a drawing, I was reluctant to go arbitrarily punching
holes.

So I bought a Progressive Electronics Model 701K "Tone and Probe Kit".

Works like a champ for following speaker wires.  Also has a telephone
adapter.

I love to cook with wine.      Sometimes I even put it in the food.
