DarwinCatholic -- always looking out for our readers.
Here's a site that will map out all registered sex offenders near your home. A little house marks the location of your home on the map, and the little colored boxes pinpoint the addresses of the offenders. If you click on the boxes, you get a picture of the person, his address, and his crime.
I'm pleased and relieved to note that the Darwins seem to live in a fairly safe area -- reassuring as I'm about to head out for a walk with the girls.
