Here's a nice 1+ footer to a not-so-grounded piece of house wiring left over from powering up my shed/lab - it was just left dangling from the rafters. I was using a phillips screwdriver as a breakout - I'm still getting sporadic discharges in the 'free' state, that are hard as hell to photo w/out a time exposure setting (which, unfortunately, my Dig. camera DOESN'T have...). Guess I just need to get a few more NST's for my hungry baby! ;)
