Maybe I need to move.

A little more about the site:

The purpose of this site is to inform the general community of sex offenders in their area in a straightforward way. Sex offender registries have been on the internet for many years, but they are hard to find and even more difficult to use. MapSexOffenders.com is simply a map so that the data can be easily viewed. Each sex offender is highlighted on the map and you can zoom in to view the offender, address, and other information. The map also links to the state registry for additional information such as the vehicles offenders drive and their convictions. Parents concerned about their neighborhood or those who are moving can use this free service to make sure they are in a safe neighborhood.
