In the late 60’s we lived on a ranger station a few miles from Broadus, MT. Once every week or two one of those huge bombers, probably a B-52, would fly over at a very low level just above the hills. You could feel the vibrations long before it flew over. They were so low you could almost hit them with a spitwad.
I was stationed at Ellsworth. I miss watching the bombers take off and land. If you can consider watching something to be fun, that was it.
