ranch with guest rooms -this trend was already evident in the 1930s, but by the 1950s the term began to become unpopular, with most establishments advertising themselves as simply 'ranches', and stressing their bona fides as real farms. Common to most of these establishments were free use of horses, while normal resorts charged customers extra for a horse ride. Guests would often ride into the surrounding hills for a camping trip. Some guests preferred to do ranch chores, and this was sometimes advertised, with such guests being advised to visit in the autumn when there were more chores. Eastern ranches often lacked cattle, but in order to maintain a Western atmosphere one New York ranch bought a bison from a zoo, and another had an entire Western town built, complete with a saloon, board sidewalks, and a dirt street. Of course, the main attraction for most tourists was the myth and adventure of the Wild West. Western ranches were likely less discriminatory, with very few ranches billing themselves as "restricted", but in the Eastern industry, this practice was common in the 1930s. In the US, guest ranches are now a long-established tradition and continue to be a vacation destination. Depending on the climate, some guest ranches are open only in the summer or winter, while others offer year-round service. Some of the activities offered at many guest ranches include horseback riding, target shooting, cattle sorting, hayrides, campfire sing-alongs, hiking, camping, whitewater rafting, zip-lining, archery and fishing. College students are often recruited to work at guest ranches during the summer months. Common jobs offered to college students include housekeeping, wrangler, dining staff, and office staff or babysitters. A number of working ranches have survived lean financial times by taking in paying guests for part of the year. Hunting ranches Some guest ranches cater to hunters. Some feature native wildlife such as whitetail deer, mule deer, bison or elk. Others feature exotic species imported from other regions and nations such as Africa and India. While many traditional ranches allow hunters and outfitters on their land to hunt native game, the act of confining game to guarantee a kill as practiced on some ranches is controversial and considered unsporting (see fair chase). The introduction of non-native species on ranches is more controversial because of concerns that these "exotics" may escape and become feral, modify the natural environment, or spread previously unknown diseases.
