Ha! "Big D", as known by everyone born in Texas, wish they had been or know how to identify it on a map is Deadwood, TX.

Deadwood, previously known as Linus, is on Farm Road 2517 some ten miles east of Carthage in eastern Panola County. In 1990 Deadwood was a dispersed rural community with a reported population of 106.

Why is it known as "Big D"?

Come on over and I will explain.
