My PSK is designed to get me home. I'll be buggin in unless my home is toast.
Other than my EDC I keep my PSK in the back of my Jeep. Even at work I'm never too far from it and as long as I can keep it moving I'll make it home. If for some reason I have to spend a few days/nights in the process I'm slowly getting prepared.
One of the bigest faults that I have is keeping too much in it. If I need to carry it I want to weight around 25-30 pounds max.
