I keep track of counties and routes, but never gave much thought as to how many of each.
21 in Florida: Monroe, Miami-Dade, Broward, Collier, Lee, Palm Beach, Martin, Indian River, Okeechobee, Highlands, De Soto, Hendry, Hardee, Glades, Brevard, Sumter, Osceola, Alachua, Putnam, St. Johns, Flagler.
7 9 in Alabama: Madison, Limestone, Lawrence, Morgan, Marshall, Etowah, Cherokee.
Can add Cullman and Blount.
So, 28 30 is my answer for now. I can't think of any others that I haven't lived near or alongside of, to count towards that total.
