TRAIL MATES: Carole, Stevie and Lisa are totally devoted to horses - and to each other. But for Carole, it seems as if there's not much she can count on except riding and the friendship of the Saddle Club. Ever since her mother died, Carole has urged her dad to go out on dates. But now she's afraid that he's getting serious about a woman whom she isn't ready to think of as a stepmother. Meanwhile, Carole's getting the last thing she needs: unwanted attention from a boy. And Stevie and Lisa aren't much help. They're busy modelling for a riding catalogue - and finding out that modelling's not all it's cracked up to be! DUDE RANCH: Stevie, Carole and Lisa gear up for the adventure of their lives when they are invited to a dude ranch. They will have a whole week of cowboy-style riding! But when they arrive, the girls soon realize there's more to the West than Hollywood shoot-outs and colourful costumes. To show a cowhand that they're not just "dumb dudes", they pitch in with chores and help on a cattle round-up, where Stevie has a run-in with a dangerous rattlesnake . . .
