This is interesting research in the Washington Post.
The most popular street name in America is "Park". Second place is "Second/2nd". Oddly, "First/1st" is fourth. I guessed before I looked at the list and thought "Main" would be #1. It's 10th.
The tree-names are also in the top ten...Oak, Maple, Pine, Cedar.
In Chicago, it's Pothole. (Not really, but it should be)
