I've been listening to a lot of Old Time Classics radio.
Every so often, they run an add for the Government (of the United States, I'm guessing, if the accents and the "State Booster Seat Requirements" on the main page are anything to go by) that urges parents to keep their kids properly confined in the car.
Children should be in a booster seat until they are taller than 4 feet 9 inches.
I am 4' 10".
Thank the Lord for that inch.
Just don't tell them about "#4".
I don't like the back seat.
Although,... I don't know... some of them look quite comfy... all you'd need would be a foot rest... might be a good reason to get a smaller butt...
