I’m guessing it’s just that someone decided to name a bunch of streets after states.
Let’s see, 'round here we have groups of streets named after…
cities in California (Idlewild, Hollywood, Lancaster…)
Trees (Maple, Poplar, Oak…)
Streets that start with the letter M (Marquette, Manistique, Monrovia, Milwaukee…)
Indian names (Navajo, Mohawk…)
And someothers I’m no doubt forgetting.
Based on that, I’m thinking ‘state names’ is the common theme.
There’s a neighborhood in Columba, SC, where the streets are all named after South Carolina colleges: Furman Ave., Limestone St., Erskine St., Citadel Ave., Clemson Ave., Converse St., Wofford Ave.
I meant to go steal one of the Furman Ave. signs before I went off to college, but never could work up the nerve.
They are all names of U.S. Navy battleships. I only know this because I have recently found an interest in naval history, as my son joined the Navy. A long history of an Army family, and he rats us out…LOL
