What sucks is nearly all states are different. I've towed from California to Florida to Washington to Missouri, and everywhere in between.
California is one of the worse states, as in the most dangerous to drive in. With 1/2 the vehicles going 70 in the left and the other 1/2 going 55mph in the right lane, getting on and off the freeway is always riskier than necessary. They stopped maintaining the roads long ago, so the right lane is usually Pothole City. You can tell when you cross into Calif with your eyes closed by your teeth chatter.
