A good example is Four Corners Monument. There is no reason to go there other than to take a stupid picture of you straddling 4 states to say you've been there. It's on Indian land and all these little shacks are set up around the monument hawking jewelry and stuff. Depressing.
But an interesting side note. The Indians drink, drive, and litter so much that the sides of the highways in that region literally sparkle in the sunlight from all the empty bottles. It's kind of beautiful.
I'm a big "collector" of destinations, but its usually for my own enjoyment, not to brag about to others. But I will probably visit Antartica one day just to be able to tell people I've been to all seven continents. Otherwise, can't see why I would want to freeze my ass off to see some penguins.
