1973 Karting National Championship race at VIR.  That's me third on grid.  My father is manning the starter.  See article HERE.  Also found HERE.

My race toy was a Mole kart like the one below.  Mine was Daytona Blue and much tidier.  Note absence of a steering wheel.  Mine was powered by a 125cc B-Bomb single cylinder, Italian engine.  HP,  I forget.  

Look, no steering wheel.  Tiller!
