One of the most inaccurate stories in a TV western is the outlaw gang that takes over a town. Dodge City at the time had about 850 citizens and they would not have allowed it. It would have turned out like the James gang in Northfield, MN, and the Dalton gang in Coffeeville, Kansas. Eighty percent of the men out west had fraught in the Civil or Mexican wars, or against the Indian tribes. Plus every man had to hunt for his next meal. A gang taking over would not have happened.
None of the green felt topped tables in the Long Branch have any stains on them- surprising in a place where spilled drinks would be an obvious common occurrence.
