Some of my fondest memories revolve around family time spent amid the natural wonders of Yellowstone National Park. There’s so much to see and do. Yet fully appreciating that abundance requires some effort. Yellowstone’s size alone makes it a challenge. At 3,500 square miles, the park is larger than Delaware and Rhode Island combined. More than 350 miles of paved highways radiate from the center of the park to its five entrances — three in Montana and two in Wyoming. The west and east gates are 100 miles apart. So while you could conceivably tour it in a day or two, you’d miss much of what makes it unique.
