Well, we didn't plow, but I learned to drive on my granddad's 1950 Willy's jeep. He had a bunch of land in N MO and left it all natural - farmed the bottom lands. Anyway, he used the jeep to get around the property. Course since we were driving in the woods in a jeep, it didn't much matter about how straight you were going.
Have fun with the hay - I'm buckin' bales alongside you (in spirit). Oh wait, you probably use a forklift, huh?
