Basically the area between Silver St. and the Kennebec River, bounded by downtown at the north end and the cemetary to the south.

It's the lower-income, higher-crime part of town, but you have to put that in perspective--it's still Maine, not Detroit. It's not the part of town I'd want to live in if I moved back, but I think the comment you're replying to makes it out to be worse than it actually is.
