I have a friend that was an electrical engineer for the navy when they were installing and testing the nuke! Some of his commentary was pretty frightening.
I do not recall ever being called a carp, I am a journeyman carp if you will, but that will not be my function in McTown. I am also a plant engineer so my work will have more to do with organization and logistics involved with construction and such.
I am assuming that you know what "Tin Knockers" are as well. That is something that I have also done back in my semi sordid past. This is all stuff that I occupied my time with when that biology degree didn't take!
