San Francisco underground icon (literally) John Law will be appearing on the History Channel's Cities of the Underworld. Scott Beale writes on Laughing Squid:

Laughing Squid's own head of special projects John Law will be featured tonight and tomorrow on The History Channel show "Cities of the Underworld" hosted by Don Wildmon, a series where Don travels the world exploring subterranean structures.

The episode with John is about San Francisco and in his segment they explore San Francisco's Word War II bunkers and talk about the San Francisco Suicide Club. John, along with assistants John Hell, Katy Bell, CJ Desoda and Simone Davalos, "kidnapped" The History Channel crew taking them on a San Francisco adventure.
