In The Event Of Nuclear War, Is There Anywhere Safer Than Brooklyn?

I've been to a fair few places in the U.S. now and have occasionally noticed a fall-out shelter or two. Particularly in urban areas, for good reason. But wow, Brooklyn must be the founder, spiritual home and capital city of fall-out shelters, because there are more of them here than there are places to post mail.

I can think of 6, within a 5 minute walk from where I'm currently sitting and it's not like I've done a substantial check for them either. Maybe I should, a map of fall-out shelters; you never know when it's gonna come in useful.

Having grown up outside the U.S., and during the very end of the Cold War, I must admit to being fairly ignorant on the places. Do you hear a siren and just go and hide? If it became crowded, would I, as a foreigner be booted out into an inhospitable wasteland (no offense Brooklyn)? Back in the day, were they well maintained and supplied?

All interesting questions. But most importantly: In the event of nuclear war, is there anywhere safer than Brooklyn?
