Just about wherever you go nowadays chances are someone’s already been there. You’d be challenged to find many places on this planet where humans haven’t already been. Virtually everywhere you go, someone’s been there before you. And worse yet, if it’s a really cool place, somebody’s probably put up a fence around it and is charging admission.
The world is changing. Adventure travel isn’t what it used to be a hundred, even fifty years ago. But that’s no reason you shouldn’t go. If you travel to where you never been, it will be your first time. The journey will still be a rewarding adventure if you approach it right. And in a sense, we are all explorers in our own right.
