Mojave phone booth

The Mojave phone booth was a lone telephone booth placed circa 1960 in the Mojave National Preserve which attracted an online following in 1997 due to its unusual location. The booth was 15 miles from the nearest interstate highway, and miles from any buildings. Its phone number was originally +1-714-733-9969, before the area code changed to 619 and then to 760; 733 is the Baker, California rate center.

Fans called the booth attempting to get a reply, and a few took trips to the booth to answer, often camping out at the site. Several callers kept recordings of their conversations. Over time, the booth became covered in graffiti, as many travelers would leave a message on it.
