By the 1920s many ranchers in Crockett County had fenced their land, preventing their neighbors from driving sheep and cattle to the railroad shipping point in Barnhart (23 miles north of here). A solution to the problem was offered by the Ozona-Barnhart Trap Co., which was organized in Ozona in 1924. By buying or leasing land for trails, traps (small pastures), pens, and water wells, the company established a corridor through which ranchers could drive their livestock to the railroad without crossing their neighbor's fences or destroying his grass supply. The main trail extended about 34 miles, from south of Ozona to Barnhart, with branch lines throughout the county. The McNutt traps (2 miles northwest), with 1340 acres of pasture, were the hub of the trail. Sale of stock to area ranchmen financed the enterprise, and operating expenses were handled by a charge per head of livestock for services used. The O. - B. Trap Co. saved the ranching industry at a time when it was the only important business in Crockett County. The need for the trail dwindled with the rise of truck transportation in the 1930s, but drives were still held until the 1950s. The O. - B. Trap Co. now leases its land for grazing or gas production.
