S'funny what we did as kids in cars.
I used to love winding the windows down in summer and fishing my hands through the airstream. Changing to an upturned hand was great fun as it caused drag.
Sticking your whole head out was the best, allowing the rushing air to sweep over your face, eyes and hair. Even dogs like doing this!
Another popular pastime at the back was being co-driver. This was either achieved without props or with one of the cool plastic toy steering wheels which had a huge suction cup so it could stick to the back of the seat in front. I loved that toy. It has a horn in the middle, a ratcheting indicator lever and a couple of switches. I seem to recall it being blue and maybe made by Casdon?
I-spy was a staple as well, which everyone could play, even the adults. I spy with my little eye something beginning with Z. I remember it so well it could be yesterday.
A similar game was spotting certain makes of car and truck, although I'm not sure how we played this now.
In my attic I have an old board game about cars. Its something I picked up at a boot sale 20 years ago. Its by Letts or Lotts I think. It was made specifically for kids in the back seat. I don't recall playing actual board games in the the car like this. Do you?
What did you do in the back seat readers? as kids I mean!
