Billerica, north of Boston: I can report missing acorns. A month ago my father-in-law and his relatives were exchanging missing-acorn stories, because the big oaks in his yard (I don't know what species) didn't produce any this year, and he's curious. He seems to think it was fairly unusual, and he's lived with those trees for decades and decades. I guess it's not just him. It would appear that something is up. Let's all hope that it's something transient.
