I don't know when this sign was put up, but it looks like it has been there a while! There is one in front of every parking space along the building, but this was the only parking space actually available; all of the others had company vans parked in them.
I am not a native of Lubbock, nor even of Texas. I was born and raised in Greenfield, Indiana, spent a couple of years living in Glasgow, Scotland, and then landed in Lubbock where I've been ever since. Have a look!
