Fast food sweet tea, ranked

I went through the drive-thru in 18 fast-food restaurants in North Alabama. The rules: The fast-food restaurants have to have locations in at least two major Alabama cities. I judged the tea on several criteria: How strong it is, how sweet it is, how much ice is in it and what kind of ice it is (because all ice isn’t created equal). Using these factors, I ranked the teas from worst to best — so you know which to avoid and which to order.
And, as always, let me know how wrong you think I am in the comments below, or if you prefer, shoot me an email to complain as well.
Now that we have that over with, let’s get to ranking.
