I recently went to Zion National Park about 45 mins NE from St George to hike The Subway. I went with my father in law, and 2 of Brittany's cousins. We had a great time and it was awesome to see the unbelievable scenery we have in our fantastic state.

You can see evidence all throughout the hike of where the river once was.
Dinosaur tracks. Amazing to believe these creatures once roamed the earth.
