Decide how much time you have for travel. A direct trip with as few stops as possible (an emergency need to get across the country, for example), can take three to four days. A sightseeing tour across America can take weeks, months or even years to complete.
Pick the places that you intend to see. Thumbing rides can make the route sporadic, but mapping out specific destinations is a good way not to miss any important American sights. Be sure to buy a professional driver's atlas, which will contain exit numbers, rest stops, emergency numbers and hotel information.
Remember cost of living varies greatly in different areas of the United States. A hamburger in New York City can cost 4 times as much as a similar burger in rural Tennessee. Anticipate your food expenses and then double the figure to stay on the safe side.
Have more than one way to get cash. Give at least 2 friends or relatives that you trust access to your funds back home. Most U.S. cities have Western Union offices. If you get in a financial jam, you can make a simple phone call to get back on track.
Use every safety tip in your arsenal. Take a friend if you can. Carry a cell phone and keep it charged. Check in with family often, giving your current location and plans. Write down plate numbers. Follow your instincts and don't hitch a ride if you feel uncomfortable for any reason.
