But have you ever seen it? I had not-until Saturday as I was driving home from my grocery run. Pulled into my hood and saw smoke...thought this is probably not good and there it was-a tree burning on the power line. I should have did some video cause it was making this high pitched almost siren sound as well. Called 911, tried to remember my address, and the story has a happy ending. In fact, now it looks as though nothing ever happened!! But I have photos to prove it!! Be safe out there.
