So I was walking to work this morning on a greenway path (my bike is a few adjustments away from being back in action), and I was daydreaming about something or other. I heard a loud but pleasant 'ring ring' and looked back to see 2 bikes coming my way, about 100 feet away. I had plenty of time to make sure I wasn't hogging the whole path and it didn't scare the S&*t out of me either. I thought they were wimpy before, but I think I'm going to outfit my bike with a bell now.
