Hi, I'm Carlos, one of the kids in Ms. Frizzle's class. When I brought my mystery rock to school, I was hoping Ms. Frizzle could tell me what kind of rock it was. But the Friz doesn't like to tell when she can show>>>That's how we ended up on a wild rock hunt in the Wild West, trying to solve my mineral mystery! We took an awesome stagecoach ride, panned for precious gems, and even explored and old mine. Sure, the going got a little rough at times--but in the end, this road trip rocked!
