One reason I'm in the process of moving closer to the suburbs is the fact that you never know who your neighbors are, but the possibility of them being a registered sex offender is far higher in my old neighborhood than the one I'm looking in now.
Nancy V. sent me this this 12-state sex offender registry that includes addresses and pictures. It stood the hair on my head straight up, I'll tell you.
Type in your address and take a peek. You may be pleased. Then again, you may be looking at creepy nasties you'll know to avoid.
