I think that for urban survival your PSK is fine.<br><br>I guess I would put some single dollar bills in there instead of the whole $50. Or maybe a combination of 2 $20s, $5 and five singles.And get four quarters instead of 3. I see that you PSK is mostly devoted to medical stuff which in urban settings is a logical thing to do. Photon is a nice thing to have. I find it hard to use knifes that don't have locks on the blades (reffering to your Swiss Army knife) but that's a personal choice. Have you ever thought about geting a multi tool instead of you knife? I see you have no signaling devices in there. Since search from the air in urban settings is not really practical I think that a whistle would do. All the best,<br><br>Matt
