It took awhile, but folks finally caught on that President Cartwright’s ranch in Virginia City, NV was the Ponderosa from Star Trek‘s contemporary, Bonanza. Cartwright himself bares a purposeful resemblance to Ben Cartwright actor Lorne Green. But no one tried to make the connection to the vice-president.
Laura Dayton was a reoccurring character on Bonanza. She was played by actress Kathie Browne who also played Deela in Wink of an Eye. VP Dayton was based on more recent images of her.
