What Canoe Pam said is true - anyone can find out where you live and even get a map to your house on the internet. Been that way for a while. At first we were somewhat protected because we did not have out street address listed in the phone book, so it just showed, First name, last name, town, state.
But there is so much info now you just have to hope no one is looking for you.
I agree, put as little info as possible on Facebook if you use it. I cringe when I see what my neighbor's 14-y.o. daughter has up there.
