College Student Travel
Your college years are a great time to travel, whether it's in the U.S. or abroad. You might have summers free to go places, whereas after you graduate, you'll (hopefully) be tied down to a job that limits your time off.
The road trip is an American classic. Just google road trip movies and you'll see. To plan your own American road trip, check out Let's Go Roadtripping USA. It's on Amazon.
If a European adventure is more what you had in mind, start with Let's Go Europe. You can find the latest edition on Amazon.
