Poop Reads must read here guys, just because I like you. This article from Lifehacker has every conceivable urban emergency and how to survive it, complete with written directions and a lot of Youtube videos. It's pretty long, I haven't even made my way through it yet, but I am going to finish it. Because I don't want to die in a fire, or get killed by a mugger, or drown in a tsunami, or get eaten by a crackhead. These are real things. These are things that happen. You best protect ya neck.
