So as I think of it constantly, here are my current thoughts: whether it be zombies, a pandemic, or global warming the outcome is roughly the same. I predict populations collapsing into smaller groups. I can imagine my neighborhood closing in. Luckily we have at least one doctor so we'd be in decent shape. It's a loop around a major street so I'd predict we barricade the road entrances and strengthen the houses at the ends with guns and shit. We'd need to plant tons of gardens to be self sufficient and I think I have enough technological knowhow to set up a solar panel network and possibly some kind of intranet. We live right by some ghettos but I suspect in exchange for some electricity (nuclear is like 1/4 of ours provided and its safeties turn it off quick) I could get a truce so that we could make it to normal stores for supplies we can't grow. Anything I miss?
