Great thread!
I have lots of early memories, mostly just random 'pictures'. This one stands out because the pics are connected...
I was about 2, and I had observed Dad put the key in the little slot near the steering wheel, and turn on the car. This was really impressive!
Later, my folks were sitting around the kitchen table, talking (bo-RING!) so I toddled over to Dad and asked for his keys.
I have no idea why he actually gave them to me, but he did.
I proceeded directly into the living room, where I had observed a similar slot in the wall, and I remember approaching it, and that's as much as I remember!
I've been this way ever since.
