Incline Village. Copies of the "Ponderosa Map", autographed by three of the Cartwrights, became souvenirs at the ranch for decades afterward, along with tin cups bearing their likenesses. Episodes that were filmed entirely or in part at the ranch bear a title plate at the end of the credits. These episodes are from the tenth season through the end of the series (1968–73). The Ponderosa experience Parking for visitors was at the highway level; only official vehicles, such as the park's Conestoga wagons, were allowed at the top of the ridge, where the park was located. Depending on the time of day, a park visit could include breakfast. Lunch, including a "Hoss Burger", could also be purchased. Estimates are that more than three million of these were sold during the park's existence. A visit to the park consisted of visitors riding up on the wagon, being "robbed" by "outlaws", and then disembarking at the main house. Adjacent to the house were the "graves" of Ben Cartwright's three wives, each of whom had given birth to one of the three (half) brothers. Graves of the Cartwrights and cook Hop Sing were later added, following the deaths of Dan Blocker (1972), Victor Sen Yung (1980), Lorne Greene (1987), and Michael Landon (1991). The house contained a less-than-realistic carved figure of Ben Cartwright sitting at his desk, and of Hop Sing working in the kitchen. The only parts of the house that actually existed were the living room, dining room, kitchen, and office. The stairs led nowhere, as the "bedrooms" were actually located on a sound stage in Hollywood. Thus, the tour of the house took very little time. The main attraction was the ranch's version of Virginia City, which was miles from the real Virginia City but immediately adjacent to the rear of the house set (on the show, the ranch was about a two-hour ride on horseback from Virginia City). There were activities such as a haunted house, panning for gold, amusements based on old-time Wild West shows, as well as concessions and souvenirs. Only the front of the ranch house was ever shown on television because a highway ran directly to the right of the house. In episodes shot in-studio, the home exterior has a backdrop of sky and trees. The ranch house was a single-story structure, although from the outside it appeared to have a second story. Little Joe's
