text: Challenges On the long trips—up to two months—the cattlemen faced many difficulties. They had to cross major rivers such as the Arkansas and the Red and innumerable smaller creeks, as well as handle the topographic challenges of canyons, badlands and low mountain ranges. The major drives typically needed to start in the spring after the rains stimulated the growth of green grasses for the grazing cattle. The spring drives, with those rains and higher water levels with the runoff, always meant more danger at the river crossings, which had no bridges. The half-wild Texas Longhorn cattle were contrary and prone to stampede with little provocation.
  The days of longest sunlight, near mid-June, were also an important consideration in the timing of drives. In addition to natural dangers, the cowboys and drovers encountered rustlers and occasional conflicts with Native Americans. The cattle drives disrupted the hunting and cultivation of crops in Indian Territory. Tribal members demanded that the trail bosses pay a toll of 10 cents per head to local tribes for the right to cross Indian lands (Oklahoma at that time was Indian Territory, governed from Fort Smith, Arkansas).
  The only woman known to run her own cattle drive traveled from Texas to Wichita using the Chisholm Trail. Margaret Borland took her family, hired hands, and 2,500 Longhorns through the trail in 1873 in search of profit for her cattle, which was worth triple in Kansas over Texas prices. She died from what was called trail fever just after arriving in Wichita, after an otherwise successful journey.
