One of the coolest things I own is a Martin Backpacker guitar, which comes with me on many an outing. It's a tiny, light version of the original, and when you sling it over your back, it's virtually weightless, allowing you to easily bring it to the beach, on a hike in the woods, or just to have with you if you come up with an idea.
It's a completely different experience playing music while you look up and watch the sun filtering through the treetops, their calm song intermingling with yours. You can find remote spaces where you can really let go and wail, such as one location I have fondly named "The Screaming Swamp."
Today, I found one such place, on the top of a mountain, no one around (yes, I cheated and drove there). Just me and the panoramic view. I sang at the top of my lungs and it felt great.
And while I didn't receive any tips for playing "out," the crows seemed to enjoy it. :)
