Trickham br/Coleman County, Texas br/31 35.275' N 99 13.860' W br/br/Text: Oldest town in county; founded about 1855 as a cowboy trading post for ranching activities of cattle baron John Chisum. During 1860-1890, it was a boisterous community at a crossroads of cattle trails. Because of notorious jokes played at local general store, "Trick'em" was suggested for name of post office here.
