I am reading the latest New Yorker, given me by neighbor. p.88 Lying under the Apple Tree,
by Alice Munro. "Cowcatchers and pincherries in the fencerows breaking into bloom before
there was a leaf on them."
I know about cowcatchers on steam locomotives. But I can find no mention of a tree or
bush so named. Not clear what region is involved.Who knows what the are?

Further on in the story, places are named that are in Great Lakes region.
