Andrew Forsthoefel was 23 years old. He’d just graduated from college and wasn’t sure what to do with his life. So he decided to walk across the United States, from his home near Philadelphia to San Francisco, through the southern states and the deserts of Nevada. He had a simple quest: to ask the people he met what advice they would have for their own 23-year-old selves. Andrew used an audio recorder to make a documentary about his experiences. I first heard excerpts from Andrews’s story on National Public Radio’s This American Life. The entire documentary is available here, at transom.org.
