Huh. I can’t believe I’m the first person to post this, but I’m hiding out in Costco.
All their entrances (at the one closest to me anyway) have the rolldown metal gates, and there’s obviously no shortage of stuff to bolster that with on the inside. There’s enough food to last to the Apocalypse, much less some random zombie outbreak, and you’d probably have a change of clothes for every day of your stay there (depending how many people you have in there with you). You’d also have memory foam mattresses and pillows, and damn comfy leather sofas.
Heck, the worst problem you’d have is that their selection of books is somewhat wanting. (Ooh, better yet, fill up a generator – and they have to have generators – with the Costco gas outside, and you can watch DVDs on top-of-the-line TVs and surf what’s left of the internet to boot.)
