Where can I research and locate sex offenders in the local LaGrange community?

This is a good site: http://www.criminaljustice.ny.gov/nsor/
You can search by county or zip code. Also, you can put in an address and you will receive an email alert when a registered sex offender moves to town. You also aren't limited to your address- if your child attends daycare, or spends time with grandparents (in NY) you can also get alerts for those areas.
