Where To Get This Card: One False Note


"What is it about the Tomas and the American West? They have connections to the notorious Alcatraz Island in San Francisco Bay. They were closely tied to the Pony Express. The Tomas pretty much owned the Gold Rush, and they can't get enough of Monument Valley. Have you guessed the connection? That's too bad, because even the Dolt . . . er, HOLT family knows. They like to celebrate their Tomas ancestry with high-adventure camping trips. After all, it's really fun to strangle each other on top of really high cliffs!"
