Boo! My last link didn't work. At least, it didn't take you to the picture I wanted to use. Let's try this instead. This is a picture of the hill behind my parents' house. It's labeled "Poteau Mountain" but it's actually called Cavanal Hill, and it is the world highest hill, according to the plaque.
It's weird, because that picture had to have been taken somewhere near my parents' house, which is sort of off the beaten track.
