I reckon hippie means different things to different people. After the war my dad (Pearl Harbor vet) left the midwest for Oregon and bought a cabin and land up the McKenzie river. Off the grid, his dream was to be self sustaining, living off the land while earning money as a craftsman and inventor. He believed everybody could live comfortably with low impact and he aimed to prove it. Sadly, his dream came to an end in an accident on his motorcycle, otherwise who knows what might have come of it.
I don’t have anything against living off the land. Some of the hippies tried to do that, and that’s fine. But hippie to me always meant dope-smoking, lazy leftists who thought they knew how the world turned but actually didn’t have a clue. However, your dad was no hippie. Just someone trying to live off the land like the trappers and mountain men of the old west.
