[Does so]

Dumb, dumb, dumb.

Depends. My USPS didn't know my address existed, so they wrote it in black marker inside the RFD box door. (It was already on the outside in big letters). :-/

Law went into effect about 1994 that all of Texas had to have a 911 address.

At that point of time, unnamed roads had a name and there was a house number at the most remote location.

Learned then that a house family had in Santo (Texas y'all) was on Lamar Street.

Did not know that 'till then.
