Summary: The best little key in my library
Review: I've been using this simple key since I was a college student in Minnesota over forty years ago. Although I now own several large comprehensive keys, this is the first key I try, even though it may not be spring and I now live in Connecticut. It will usually send me quite easily at least to a family, probably to a genus, getting me through what might be the most annoying portion of my larger keys.
