Choose the sights you'd like to see. Using a guidebook of the United States, or an internet site such as Google Maps, choose which sights interest you the most, and note them on a map. Theme road trips can add adventure to any drive. Many movies incorporate road trips in their plots such as, "Thelma and Louise," "Elizabethtown" and "Highway." Following the routes characters have taken in your favorite movie can place you right in the middle of the action. The Food Network and the Travel Channel also feature restaurants and sites provided by locals that are not noted in most guidebooks.
Choose a route. Choose a route that fits your budget, time constraints and allows you to see most of the sights you have marked on your map. If time is your biggest issue, try to use as many freeways as possible. If you'd like to take in the sights and enjoy the view, use back roads. Google Maps is a great resource for step-by-step instructions.
Map out lodging, restaurants and gas stations beforehand. Make reservations at hotels along your route before you leave and mark them on your map. By mapping them out on Google Maps, you'll be able to see how long your driving time is between destinations, and when you'll need gas. Mark restaurants and rest stops so you know where the next one is when you're on the road.
Pack supplies. You'll need all of your maps, itineraries, some snacks and water. Pack a first aid kit, and a car emergency kit.
