One of my primary passions in life is adventure. The first picture shown is of the sahara desert, the worlds largest desert. The second picture is of the Amazon rainforest, the worlds largest rainforest. The third picture is of the mariana trench, the deepest known place under the ocean. The fourth picture is of Vincent Massif, the tallest peak in Antarctica, AKA- the bottom of the world. I'd say that all of these places are practical locations to travel to.
