Do I carry a cell phone while riding ? Yes. But it sits either in a pocket or in a fanny pack for emegencies only.
Do I use ear buds ? Yes I do but I never, ever use them while riding. I like to be able to hear other cyclists and the traffic.
Dogs on leashes ? We don't own a dog and our three Maine Coon cats who are all dog sized at 15 pounds are too busy conserving energy by sleeping in the sun.
