It sounds like you have a nice tractor there Robert. Good thing you pulled the pistons out though.
As far as traveling, I agree with you, I'm sure he had an easier time than today. During World War 2, he traveled all over in regard to the MG-1s - he had unlimited gasoline ration stamps, and sometimes had an MP ride on each fender when he was entering a base or restricted zone. Later on, he traveled troubleshooting tractors. He preferred to fly, probably in the 50s on DC-6 or Constellations for long flights; DC-3s for short hops, and maybe even single engine planes to get into the really remote areas. When he went to Guatemala to put several OC-18s back into service building the Pan-American highway, he flew into a small airport where they picked him up in a car, then a Jeep, then by mule way up into the mountains. His biggest regret was that my grandmother hated to travel and would never go with him. He wanted to take her back to some of the best places he had been.
