The Jim Crow Era's Guide to Safe Travel for African-Americans

The road trip. The freedom to get behind the wheel and explore the country is a tradition that goes back nearly a century. But it's a freedom that not all Americans have enjoyed. Back in the 1930s, the hazards facing one group of travelers inspired the creation of a unique travel guide. It was called The Green Book, and for 30 years it told African-American travelers where they'd be welcome to stay the night, get a bite to eat, or fill up with gas. We report on one woman's quest to preserve the memory of The Green Book -- a piece of history she says remains relevant in 21st century America.
