Well, this one really depends on the suburb.

If its in Detroit, well then you have already gotten rid of all the neighbors, and are having to fend for yourself from raiders. It isn't going to get much worse.

If it is in Portland... and you are conservative, or liberal (old liberal, not neo-liberal) as growers of food usually are, then you are going to find yourself on the wrong end of angry crowds. And then angry crowds that are hungry.

The US is going to split up. And so, if you are a conservative hold out in a coastal state, you are going to find yourself surrounded by enemies. (or vice versa

But there are many cities that have a decent water source and local power. That have a rise in employment rate. That have a lot of good people all around. Well then you will probably be all right.

The big thing that is going to change is small community sized power generation. And this might not be doable in suburban areas. Regulations and permitting will not permit you to be self-sufficient. (even solar... read the thing they have you sign before you can install your solar and the one before you can line-tie the solar)
