WICHITA, Kan. (AP) — Kansas residents are celebrating the 150th anniversary of the Chisholm Trail, which was used as a cattle pipeline from ranches in Texas to railroads in Kansas. The Wichita Eagle reports that a herd of cows with 15 cowboys, five chuck wagons and 40 helpers drove along a portion of the trail this week. They made appearances near Wellington, Mayfield, Clearwater and at the future site of the Union Stockyards in south Wichita. The cattle drive began last week in Oklahoma and ended Saturday, 90 miles north in Sedgwick County. The event was organized by the O-K Chisholm Trail Cattle Drovers Association. It's meant to echo cattle drives from 150 years ago, when the trail boosted the Kansas economy by promoting the railroad industry and making ranching profitable.
