I got pulled over in Tennessee. They saw I had Arizona plates and assumed I was smuggling for the drug cartels, then pulled me over and searched my vehicle. They didn't find anything. But I kept it cool and they were reasonably polite. Still, it was a royal pain in the butt. Their pretext for pulling me over was that I was "following too close," but it was outside of Memphis at the tail end of rush hour, so traffic was pretty thick and everyone could be perceived as "following too close."
After that, I decided I would never travel through Tennessee again. Sorry, Tennessee.
