It's ironic that aerobic walking has caused more close calls with crazy car drivers than bicycling did. True. Busy intersections can be really dangerous and there have been many close calls with turning morons that don't look for pedestrians. I already knew that 4-wheelers were stupid messengers from hell from my 100,000+ miles aboard a bike, but now my experience as a walker just proves that these jerkoffs are murderers. What do I have to do, walk in parks to stay away from these rabid dogs? I'll probably get mugged if I do that. And then the mugger will drive away in his car. Fothermuckers.
