Yellowstone, 1977, part 2

Ah, the wild majesty of, well, we’re not quite sure what these Yellowstone National Park visitors were viewing. Probably not bears. Whatever it might have been, it apparently wasn’t as interesting to photographer J. Schmidt as the cars the visitors used to get in and around the park. So while we can only guess at what fascinated the folks in these photos from Yellowstone’s Photo Collection, we’d probably have better luck identifying the vehicles. What do you see?
