Book excerpt: The fourth and final installment in this choose-your-own-trail series takes you all the way to Oregon Territory—if you make the right choices. The end of the Oregon Trail is near, young pioneer—the final leg of your journey starts here. But, do you have the grit to make it to Oregon City? The wild frontier is full of risks and unpredictable surprises! It's 1850 and you've been traveling for more than three months with your family, covered wagon, and oxen. There are holes in the bottoms of your shoes. You've faced grizzly bears, traded with merchants, and wild bandits. Oregon City is so close you can taste it, but there are still weeks of dangerous frontier travel ahead of you. So which path will you choose? With twenty-two possible endings, every decision counts!
