Waaaaay back in my Navy days, our ship was going through a “yard period” - First in drydock in Long Beach, followed by shipyard work at National Steel & Shipbuilding in San Diego, just down the road from the 32nd Street Naval Station.
More than half the shipyard workers were Wetbacks - yep, that’s what they were called back then so don’t give me any PC correction therapy.
Lot of guys I knew then talked about going to work “in the yards” when they got out. I left the area and went north and became a plumber.
Ike kicked out the Wetbacks in 1954. Read about it here:
