The Fort Worth Stockyards is a National Historic District located in Fort Worth, Texas north of the central business district.
The stockyards are a former livestock market which operated under various owners from 1866.
The "Fort Worth" crease seen on cowboy hats back in the 1800's were worn by the cattle owners or the "money guys" at the stock yards to look good.
The old "Fort Worth" crease seen on a cowboy hat normally has a 3.5" brim and a "cow kick" in the front and a "cow kick" in the back.
The Fort Worth Stockyards are the last standing stockyards in the United States.
Some Fort Worth volunteers wearing their "Fort Worth" crease on their cowboy hat still run the cattle drives today.
They do it so that people can see what it was like in the 1800s.
