In the 60’s or 70’s there was a lot of people with CB’s and special car radios. I remember they were often stolen out of cars in our area (NY/NJ). Police recommended putting your name and even social security number on them. A friend of mine had a big and expensive entertainment tv, stereo, radio thing. Her 5 year old proudly carved his name on it do no one would steal it. Years later it is a funny story but it wasn’t when it happened.
