Alone in the wild?

Being alone in the wild... What does that mean to you? What constitutes as alone? Sure, if you go by the dictionary definition, it means you're completely on your own- so maybe that isn't the right word. But what is alone enough? Is it enough to have a few trees blocking the highway from view? No cell reception? No one else around for miles? Well how about we go far enough out so that the highway isn't even an issue, nix the phone for sure, but let's keep a friend or two to be alone with. That's about right for me. I love hiking and camping in places where that's just what I can do. Hike through dense trees on mountain sides with a small handful of friends. Sometimes in silence, sometimes with conversation. Then make camp by a body of water. Split apart from the companions to collect your thoughts and find peace. Sit by a lake, a river, or a stream and drop a hook in to catch dinner. Then it finds you.
No buzz of cell phones,
no hum of power lines,
no horns blaring or neighbors screaming.
Just a trickling current or whispering waves,
birds chirping,
grass tickling and fish will be nibbling.
Hear the soft, distant laughter of a friend....
I think this must be what Chris McCandless was looking for. But was it selfish not to share those moments? To keep them all to himself? Maybe. Maybe he needed that.
