1 Never leave your pack in the car. No matter if you're at a rest stop and just using the bathroom. No matter if removing your pack offends the driver. "Without your pack," Ethan warns, "you are pretty much naked on the side of the road."
2 Nothing is guaranteed. Plan to move only 60 to 100 miles a day, while remembering that no plan is fail-safe: Ethan once spent three days at the same truck stop in Illinois.
3 Drink copious amounts of water. Even if you're not thirsty, fill your container of water at every stop. You never know when you might need it.
4 Claim ignorance of hitchhiking law if confronted by authorities. You may get a ride to the next county!
5 If you feel threatened, get out of the car. Ask to be let out at the next on-ramp or truck stop. If the driver refuses, say you feel sick. According to Ethan, that one works every time.
