This might have been posted before, since I didn't read through the thread but....
The Land! The United States has a HUGE variety of geography, natural wonders, incredible scenery, and pristine wilderness! Subtropical Florida, arctic Alaska, the stark beauty of the Southwest, the App. Mnts, salt marshes, the endless prairie, miles and miles of forest. I could spend my whole life exploring all 50 states and not get tired of it.
Good grief, let's hope we can preserve and conserve as much as we can.
