I hope I put this in the right forum, because it won't belong in the EZ, and it sure isn't Nonsense.
A friend sent me a link to this site today, I don't think it works in my area, but I know a lot of people here are from the US, so you may find this useful, especially if you have kids. This site, after you input your address, tells you if there are any sex offenders (convicted) living in your area.
