One street here in Nashville, TN, went for several years without any speed limit signs along its three-mile length. Then, one day, it suddenly had signs every half-mile or so. I suspect that someone probably argued their way out of a speeding ticket on the grounds that there weren't any posted limits. Tennessee doesn't have any default speed limits that I am aware of, although one can always be cited for "reckless driving".
