cool website

I hate when strange phone numbers are on the caller ID and you have no idea where they are from so I google the area code a lot. Well I found this cool website. it is http://www.reversephonedetective.com/
you type in the phone number and it will tell you the city and state the number is from. It doesn't give the person's name but at least you can tell what part of the country is calling you. I thought it was pretty cool! and its free!
