It stood on a corner by a grocery store I used to go to when I first came to Arizona.

The return gave the street number and the building letter.

The gate to the complex stood open.

I pulled into a visitor space and walked over to the directory board next to the call box.

The board was backlit glass with black lettering under a clear plastic cover.
