My OM is still a Radio Ham.
His views on CB had better not be expressed here, but as a G3xxx he has been in the game a very long time. (Early 1950s)
Now CB has matured, the parallels with Amateur Radio are very similar and the comment above regards the isolationist nature are very relevant.
I never took up Amateur Radio, having been subjected to it from a very early age and CB was not an option due to the above. I was offered one once with a second hand car I bought, but managed to negotiate a better price without it. The guy thought I was mental not wanting it at the height of the CB boom.
I think there are huge parallels between the two, even down to seeing the 'home made' table supports in the camper van. The language is very similar too. DX, QSL, Whips etc, plus the need to find high ground etc. I don't need any of the terminology or frequency info explaining, I think I was born with it ingrained in my DNA, despite never having taken it all up.
Maybe there are parallels to be had between digital and film?
A very interesting thread.
