Remember the poll description. 1 million plus population cities in their region today. For example, Honolulu city is 350k but Oahu is 950k+. Tampa city is 350k but the Tampa Bay region is 4.3 million. So, small cities with big metros count. Orlando is 2.3 million, Atlanta metro 4 million, etc.
Things to remember:
- about 1 million plus population in the early 21st century
- Mass depopulation of the Earth (pick the scenario)
- up to 20 years after the fall (you've been there a while and survived) - but if you want to describe a place during the fall or earlier go ahead.
- What city(s) would you choose for a specific apocalypse?
One could choose islands with lower populations or mountain locations. Those are the common choices because we think a big wall will keep us safe. Those towns will be foraging, raiding parties everywhere. Town wars... farms without alignment are toast.
Your one of the leaders, hiding in plain sight. People are flocking to your area...maybe.
I see why SanFran was attractive. Tampa is the same thing really except smaller which is why i chose it. LA is a good location. I lived there for almost a decade. The mountains are barriers, but it's very big. One 15m are down to 50-500k things would be tough if not interesting though. 1000 people would be a dot on the former great city. Aliens, Virus, flooding, Zombies run rampant through LA, but for rebuilding Palace Verde and the upper Mountain range are good high grounds. The city itself is of little use unless your raiding jewelry mart, but some of the towns are great opportunities for a new community.
I had 3:
Honolulu (agriculture, fishing, naval base, actually oahu is about 1 million people) - zombie apocalypse, virus strain, uplift race failure,
Tampa Bay (multiple peninsulas/islands, military base, extensive medical resources, agriculture, and fishing) - same as above
Orlando (Other) (lots of agriculture, hotels to hold up in and turn into communities, the Gaylord is enormous, Cape Canaveral is close with some military assets, freeways are barriers) and a lot of resources. - Virus, uplift failed, limited nuclear war, maybe asteroid hit.
Other options in the world are many:
Denver (agriculture, defensive position by mountains, central location) - limited nuclear war/alien invasion, uplifted race failure, asteroid hit...
Tokyo / London - capitals of large island states
Hong Kong - natural defenses, harbor.
St Petersburg - Remember, Russia was ruled from St Petersburg. It has access to Asia and Europe.
New York - It has a strategic location. However not a lot of agriculture. Would depend on hunting, trade and fishing.
