Only Three to a Bed (S03E12)

The boys eagerly accept a vacation offer, unaware that their getaway revolves around capturing and training wild horses. They arrive at a boarding house near the horse territory, where they meet a group of travelers stranded due to a broken-down coach. Among them is Beegee, a woman searching for a husband who takes a keen interest in both Heyes and the Kid. There's also a devout man whose sister has taken a liking to the Kid. Meanwhile, the boys face off against a ranch owner who believes the horses are his. It seems the only way to resolve the situation might involve drastic measures to protect "their" horses.
