My Chatham has a repuation for teenage pregnancies, crime, its full of what we call "Chavs" that like to reap havoc and cause nusiance.
The areas outside of the town are nice, I lived in Walderslade which is 10 minutes away but when I had my DD (I was 23, now I'm 25) I got given accomadation in Chatham as there was no room for me at my parents.
It used to be a nice place to live when I was younger but it has really gone downhill, but I would rather live here in Chatham then relocate to London.
There is some historical attractions here in Chatham, we have Dicken's World which is a indoor theme park based on the Dickens Era. Plus the Historical Dockyard etc, but I wouldn't go out my way to visit any of these.
Your Chatham sounds pretty nice
