It was not a good weekend to be a pedestrian. One of the weekend's three car-related homicides killed Chin Up Chin Up bassist Chris Saathoff (Friendster profile here). Blogger Mimi Smartypants was there. (Coincidentally, the Tribune's Transportation section on Sunday looked at what's being done to make cars less dangerous for pedestrians. Not enough, obviously. Cars kill more than 43,000 people a year in the U.S., and about 12 percent are innocent bystanders, the equivalent of one Sept. 11 every seven months.)
