How I know I have entered the south..
If I order "sweet tea" and the wait-staff does not point at the sugar and sweet-n-low on the table.
That's a high 90% indication I am in the "south".
Florida may not always be the South... the paradox that comes from being as far east as it is south. Even Ocala and Winter Haven are overun with Michigan and New Yorkers now days.
Oklahoma is OK... some parts or southern... others , western buy so far I dont find many "yankees" around here.
Parts of Michigan may be in the south... during WW2 much of the south went up and stayed. In some places you find grits easier than german sausage. While I was away from Michigan it seems that a great deal of that state was taked over by some mutated lumberjack-redneck- Jerry Springer- love child- strain of humanoid. Maybe that's a few years of Dutch culture gone awry in the big Piney woods? The "sweet tea" test is hit or miss in Michigan.
The Sweet Tea test in not valid in a Cracker Barrel.
