Ooof, glad you didn't lose power. I have spent the last several days being grateful that we had some arborists remove a "dead leader" (a secondary trunk that didn't make it, I think?) from the enormous Chinese or Siberian elm that straddles the property lines back by the alley. I don't want to take it out before we have to, because it shades the house in hot weather. But it's capable of doing a lot of damage when it goes, and it produces sticks and larger dead branches as if that were its main business.

Also a lot of scions, but that's not as much of a problem.
