So I merrily started cutting plaster with my sawzall on my outline for the new door, got a big flash back in the wall and heard my wife yelling from upstairs that the power was out. I had sliced through the hidden electric service to the upstairs (a separate service). I had no idea that line was in there! I had to get an electrician friend to come a run a new line up from the box, no big deal but it was a good lesson to investigate a little more before charging ahead.

Yikes. I've never done work (several times) that resulted in sparks!
