Build a climbing structure from PVC pipe while teaching Young Lad to use tools: measuring tape, screwdriver, joining pieces in straight lines and in angles, tapping hammer.
Later he climbs all over it and learns to reach while steadying himself, getting up and down and in and out safely, how big his actual parts are as he squeezes through a space barely bigger than he.
Watching remote control trucks, trailers, fire engines, bulldozers and the men who build and operate them fascinates both these guys. They discuss how each piece of machinery works, what it's named and why, where it can be found... The chat goes on and on all the while sinking the seeds for an education that will last a lifetime.
