I am trying to retrace a trip my grandparents took in 1933. I have names of campgrounds but after 82 years most all of them are gone accept the ones in national parks. I am wondering if anyone knows of an archive of old campground directories that might give me a clue as to were these campgrounds were.
The trip originated in Cleveland Ohio and covered the Chicago Worlds Fair, Yellowstone, Bryce, Zion, and the Grand Canyon.
