I've been there a few times. Just driving through though, not actually roaming around. You can sometimes see the smoke even from a distance though.
The roads aren't all closed?
I kinda just want to meet and talk to the seven remaining residents. You know, find out what their deal is.
Some parts of the roads were closed off, but you can still drive through the town. At least you could years ago anyway.
I'd imagine they have strong ties to the town going back generations. Some people just don't want to leave home no matter how dangerous it is. Either that or they're just kooks.
