Same thing happened where I'm from, Illinois, a decade ago or so. They were basically all wiped out. However the past few times I've visited I've actually noticed both young ash trees and old "dead" trees that had been cut down to the stump with new growth. It makes me wonder if there'll be new a balance struck where there will be ash trees, and there will be ash borer, just fewer of each.
