For nearly a century, people have been enjoying the five-and-a-half-mile Toonerville Trolley wilderness train ride. Today Brad and I are aboard the narrow-gauge train that starts out near Soo Junction in Michigan's Upper Peninsula. From my vantage point in the front car, I am getting an up-close view of a pair of sandhill cranes. From the rear car, Brad has already seen a black bear at a distance.
