The theme park in California that Goldrush Park, the Wild West amusement park, is modeled after is Knott's Berry Farm, about 7 miles from Disneyland. In 1940, Walter Knott began constructing a replica Ghost Town on the property, and the first ride, the Calico Log Ride opened in 1969.
The two cookbooks seen in the opening credits are Treatise on Cake Making from 1935, and The Wine and Food Menu Book by Andre Simon in 1956.
