"My whole life is, has, and will always be one continuous Walkabout. We all at some point will go on our own. You just don't know how, when, or where - be it physically, intellectually or emotionally - you will at some point go on your own Walkabout"
Urban Dictionary has this definition of a Walkabout:
"A spontaneous journey through the wilderness of one's choosing in an effort to satisfy one's itchy feet, a need to be elsewhere, the craving for the open road, that space over the horizon...yes... something like that... you can't quite touch it so you have to go find it because it's you just know it's there...Or maybe it just feels good to go walking around ... ;-) Yeah. It's WALKABOUT."
