Judy's diner was filled with rodeo pictures. Inside Carrie/Laura's house there was a white horse in front of a blue plate (and this caught Cooper's attention just after he'd been looking at the dead man in the chair).
It's interesting that the pendant was upside down from the way that a lucky horseshoe would be displayed. When they're like the one around Carrie/Laura's neck, the luck is said to be running out. When they're the other way around, it's like a glass which holds luck. Just do an image search for "horseshoe pendant" and you'll see that they're overwhelmingly rotated 180 degrees from Carrie's/Laura's pendant.
