My guess is that I'm not the only parent on the planet who is a bit squirrelly about having a son learn to drive. My guess is that fear typically sets in around age 13 or so. Not me and my overachieving and amusing kid. His feet can't come close to reaching the pedals, but he can steer a tractor. Not just a little lawn tractor, but a full-size Kubota farm tractor. And that's a good thing when mama's car is parked between Point A and Point B of "Adventures in Tractor Driving 101" as taught by Grampa LD.
Strangely, I'm pretty sure LD would have sooner eaten granite gravel before putting me or my brother behind the wheel of any such vehicle when we were only barely at the midpoint between four and five years old. My how adding the "grand" prefix to parent changes things.
Note how, except to redirect a certain kid's gaze forward, LD's hand doesn't even get near the steering wheel. And how Luke wisely stays four legs and two steps ahead of the oncoming heavy machinery.
