Warning about old phone lines in attic spaces

I was fishing a new drop in a 1970s house in Boise and my drill bit hit a live, unmarked 48V phone line, causing a small flash and a tripped breaker. I now carry a non-contact voltage tester and check every single joist cavity before I drill. Anyone else have a close call with hidden voltage they want to share?

That "small flash" you mentioned is no joke. I was helping my uncle rewire his old farmhouse and we found a whole nest of cloth wrapped wires just hanging loose in a wall. They were dead, but it looked like a mouse had been chewing on them for years. Makes you wonder what else is hiding in these old places.

My grandpa's barn had the same cloth wiring mess.
