Runners and Cars, as well as a Useful Link

There was an article in the New York Times a little while back about runners and cars.  When I can, I like to avoid running with cars, but, unfortunately, living in an urban area, that's sometimes difficult.  I usually try to defer to cars, but it can annoy me when cars don't yield to me when I am in a cross walk.  Right now, on weekends, I like running in Rock Creek Park on Beach Drive.  At least a portion of that road is closed to vehicular traffic.
I also discovered a useful link, that lets you see what your pace is based on mileage run and distance traveled.
