The roads are littered with refuse but they might get picked up twice a year. I have my eye tuned to the cigs and see them even at speed most times.

I have had my Instinct 2 Garmin watch which has the heart rate but trying to see metrics on my wrist was a pain. The Edge is really nice to have for better display and I love the climb feature to show the grade of the current climb and distance to the top.
