For anyone traveling 301 north of TV, make sure you are watching the plethora of speed zone changes closely, as some of these little towns use speeding tickets as a major source of revenue.
Although once so notorious as a speed trap that AAA paid for signs warning motorists (they also paid for signs coming into Lawtey), Waldo recently disbanded its corrupt police force. You can still see a bunch of their police cars parked in various locations next to 301, but they don't have an LEO in them.

Hawthorne, Starke and Lawtey however still have active speed traps so just be careful. Not to mention that there are zillions of traffic lights on 301 and although Google Maps and your GPS may say using 301 is quicker, I have found that going to Jax or points north on I-95 it is a much nicer (and quicker) trip going through Salt Springs, Palatka and then getting on I-95 through Hastings.
Not to mention much more scenic and enjoyable.
