Billiards
In the Goofs section, someone said that "pocket billiards as we know it today (using striped, numbered object balls) would not have been played in the American West of the 1870s, having only been developed in the early decades of the twentieth century; the immediate forerunner of pocket billiards (using solid-colored, unnumbered balls) wasn't invented until around 1900."
Okay, what sort of billiards game would Morgan have been playing with Bob Hatch when he was assassinated? What pool games did they play in the Old West in the 1880s?
Serious question, I'm curious.
I intend to live forever.
So far, so good.
