Have you ever traveled across the country? Most specifically, have you ever traveled across the country for under $500?
It seems totally impossible, but one young traveler figured out the secret. Derek Low took a journey around the United States for 15 days, using only Amtrak to get around. Though trains take much longer than planes, the fares are considerably cheaper - not to mention more scenic. They're the perfect alternative for young travelers on a budget, and Low's photos from his trip are simply spectacular.
