In 1935 the industry boomed, and Western railroad companies advertised destinations to paying guests. Airlines and travel bureaus also began to enter the business in this period. The University of Wyoming began to offer a degree in recreational ranching, and one could take a four-year course in dude wrangling. Most of the patrons hailed from New York in this time. As the trips became more popular and less affluent people began to become interested, there was an economic incentive to establishing lower cost dude ranches in the East, including in New York State. In 1943 the Eastern Dude Ranchers' Association was formed. Throughout the 1940s business remained good, as wars throughout the rest of the world made foreign travel less attractive.
