Sorry to break the bad news to those of you who live in Colorado, but, like California, a bicycle is considered a vehicle and earphones are illegal when operating a vehicle in Colorado too.

I've been seeing more and more riders with earphones. They worry me because they don't acknowledge me when I pass, most of them don't hear me when I yell, on your left! I don't worry about them getting hurt if they swerve and hit me, that's their problem, but I do care if I get hurt!
