Unbearable

I'm scanning vintage postcards and photo sets for Ebay today.
I have a bunch of them, including a set of views from 1940s Yellowstone National Park. Here's one of them - a shot of tourists feeding bears along the roadside.
We now know what irresponsible insanity this is, but as late as the 1960s people went to Yellowstone with the intention of feeding bears from their cars.
I think I mentioned earlier than when my parents took me to Yellowstone in the summer of 1956, we counted 29 bears along the roads during our two days in the park.
The National Park Service has pretty well stamped this practice out and the park's bears no longer see park traffic as a food source.
