Dayum! My father would have loved it. He rode a similar scooter 2-3 miles each way to the grocery store / shopping center when he could not drive a car anymore. He would not let his disability tie him down.
Discouragement, desperation, and despair are the ultimate disability. imo
Props to your dad for keep his spirit strong, not everyone can do that.
“The most dangerous man to any government is the man who is able to think things out... without regard to the prevailing superstitions and taboos. Almost inevitably he comes to the conclusion that the government he lives under is dishonest, insane, intolerable.” ~ H. L. Mencken
