For those who like a bit of history and have some time to wander down some Internet rabbit holes:
Robbins Barstow filmed his family for five summer camping trips as they traveled around the 48 states. His obituary is here and the archives of his many films are linked here - Part 1 and 2 of America's Wonderland chronicles his family camping cross country trips. If you have ever camped with family or wonder what life looked like in the mid fifties across many familiar sites in our country, take a look. Amazing to see this young mom camping and traveling in a dress!
