I didn't notice any. In the woods across the street there many, many more dead ash, lots have fallen too. If I was staying here, I'd grab some for firewood, no need to season. Where I'm going, I'm going pellets this time.
I counted 12 dead ash trees in my neighbor's yard, tall trees too. One fell a week ago and missed his house by a few feet, it broke off 10 feet from the bottom. Lots of great firewood though.
