when you camp with someone else, later on you can reminisce, 'hey remember this, or remember when that happened...' when your solo theres noone but nature to share the experience with. i like both ways.
Had a very long conversation with a very old crow, with many white/grey feathers, who decided to join me in my camp once a few years back. He was totally unfazed by me and I'm sure he understood what I was saying!
When you're on your own you are, at least, guaranteed intelligent conversation...
I'll get my coat.
