this!!! When you all get bugged out you will think you're safe but you will really be in the backyard/hunting grounds/territory of those of us that were raised in the hills. We know every tree, hill, ditch, cave, spring and hiding spot around our land. We will not take kindly to city folk invading our resources. Stay in your city where you chose to live.
As someone who has evacuated from New Orleans and a zombie apocalypse lover, it is a head scratcher about all the possibilities.
If a fictional or even real medical outbreak happened, the plan would be for people to stay at home and the authorities would drop off supplies. It just happened when a Great Lake went bad.
Hurricane evacuation is predicable, and while thousands were stranded during Katrina, all my friends left in plenty of time as did most New Orleanians.
But if things got really bad, like a nuclear strike or a meteor hit, then going to Ukiah may not be an option anyway. Likely whoever has an underground bunker with water and air filtration will survive.
I think a story like The Road, which was unsaid what happened, is not even fictionally possible: a disaster which destroyed the infrastructure (food/energy) but not kill almost everyone.
Zombie stories are the opposite where everyone dies but the infrastructure remains. Then skipping out to Ukiah seems attractive.
