The only lead to a poisoned female found in New York is that she had just returned from an authentic Old West-style holiday resort in Arizona. The poison takes about 10 hours to take affect so this means she was actually poisoned in Arizona. But the local sheriff won't help them, as it could damage the towns only attraction. Castle comes up with a plan to go there undercover with Beckett as newly-weds. They soon find, backed up by local Sheriff Conklin and by Esposito and Ryan, that the victim was on the trail of both her ancestry and the lost gold of a 19th century major hold-up. Resort staff provides several suspects.

The ranch activities they circled on their brochure are: Map Reading (Castle), Hog-Tying (Beckett), Harmonica for Beginners (Castle), Cowboy Saloon (Castle), Gunspinning (Beckett), Western Dancing (Beckett).
That's why Castle was in the Saloon. Castle plays the harmonica (which he just learned) at their campfire. Castle is carrying the map when they go out searching, and he says "according to the map" so there's a reference in the dialog, too.
Beckett's black costume looks ideal for gunspinning, which she eventually demonstrates. No apparent sign of Western dancing. She does lasso Castle, which is probably a family-friendly nod to hog-tying, but "lasso and roping" was a separate class on the list. See more
The stagecoach that Castle and Beckett arrive at the dude ranch in says 'Spearfish - Deadwood Stage'. The stagecoach must have been borrowed from South Dakota. Since the dude ranch is in Arizona, it should say something like 'Tombstone - Agua Caliente Stage'. See more
Whitney Williams, 22. She went into convulsions on the E-train. In and out of consciousness ever since.
I want CBC and an EKG. Any sign of drugs on her?
Nothing. But at one point, she said someone did this to her.
Whitney, can you tell me what happened?
The "Castle" title card features an Old West motif with desert and cacti, along with accompanying Old West-style music. See more
