After I talked about that guy in my pop-up camper my sis happened to send me this http://www.familywatchdog.us/ It tells you where any criminals live, in YOUR neighborhood. I didn't believe it could be real, at first. Then thought how it must be illegal to put namkes & such on the computer if it's not true. Also, it's just a matter of public record.
You just write your street & city & zip and it comes up with a map of your area & marking the adresses of the offenders.
(On that 1st part, since I wasn't sure if I wanted to write my own street, I wrote the name of the street around the block.)
