I hike. I hike a lot. I get outside to enjoy nature, reset my internal batteries and just listen and see the beauty of the natural world. More and more, I find people carrying around stupid bluetooth speakers and blasting music when they hike, completely distrubing my mood and serenity. You want to listen to music in public, put your headphones on. Not doing this is completely disrespectful to those people around you. It's no different than secondhand smoke in my mind. I golf, fairly often, and on Sunday afternoons, I'll have a small radio or bluetooth speaker on, so I can hear Uke. I can hear it when I'm in the cart, but I can't hear it when I'm hitting my ball. This has not been my experience with people & music on the golf course.
