I take precautions in everything I do....but, if someone wants to get your information they can. All they have to do you purchase (for a very small fee) a web search and they get everything. I know this because my friend did this to find her ex-husband. She found him - where he works, lives, phone numbers, who his neigbors are, who lives in the house, where he banks, so on and so....
so listing your state is definetly no big deal...
