This reminds me, I did have to yell at a guy earlier in the week on the MUP (which I hate riding, but there are short sections where it's necessary to get to my house). He was weaving all over and looking behind him (at who or what, I don't know). I was oncoming and it was becoming apparent that if I didn't say something it would end badly. I hollered "eyes forward" and he about jumped off his saddle. In the same spot a few years ago there was a woman on a bike watching her granddaughter on a bike behind her. My son was on a trail-a-bike behind me and we were headed towards collision. I hollered to get her attention and move to one side and her response was "well, I need to watch my granddaughter." I pointed out that her GDD should be IN FRONT of her, then.

I really wonder how some people have made it beyond adulthood, sometimes.
