That's what kids are for!
Starting at about age 6.
And city folks wonder how farm and ranch kids learn to drive at such young ages...
Exactly.
I don’t recall how old I was, probably 6-7. Dad put the truck in lowest gear (we called it compound) and he would jump out and shovel silage into bunks as I steered the truck parallel to the feed bunks. That was in the late 1950s.
