I remember rotary telephones. Are you old enough to have ever used one on a regular basis? Just wonderin'.
Things I remember:
Rotary phones were the only kind of phone. When the push button phones came out, I asked my mom why we didn't get one. She said it costs extra.
Telephone numbers that began with an exchange name: I grew up with Emerson 3-7177. "Emerson", was sometimes called "EM", what we now would just say 36.
Seatbelts were optional equipment. In fact, I still remember when you got into a car that had seatbelts and you put them on, the driver would note that you didn't trust his driving.
McDonalds only sold hamburgers, cheeseburgers, fries (what is now considered small), sodas, and "triple thick shakes" (they couldn't call them milk shakes because there was no milk in them).
I was in high school when I saw my first color tv. The rich kid that lived in the house that had a view of the lake had one, and only one, in his house.
