>Also what's up with the people hiking (by themselves) with a bluetooth speaker. You're by yourself, in nature. If you want to listen to music wear headphones!!

I'm baffled by this too, but I think some people get accustomed to just having a soundtrack around them at all times, like they're living in a Hollywood movie. It gets to the point where they actually sleep with something always on (in the old days that would be a TV, not sure today. Probably a podcast)
