What is the number one, must-see attraction in the state of Wyoming? Any guesses?

Have you ever thought about just how big the United States is? I once heard an interview with a band on their first U.S. tour. They said they realized how big this country is when they traveled from one side in shorts and flip-flops to the other side where they quickly needed to change into long pants and coats. And which such a large piece of land, comes many sights to see.

Ah, tourism.

It's easy to say that each state has something unique to offer, but what is the best of the best? PopSugar.com set out to answer this with their list, "50 States of Unbelievable Tourist Attractions." If you had family or friends passing through, what would you tell them that they have to see?

Admit it, you thought they would pick Yellowstone National Park. I won't lie, that's what I thought. I'm learning that it's always a toss up between these mammoth attractions. PopSugar raved about the beauty as well as the activities one can do on their visit.
