Chris; Good points, as always. But I may be approaching this from a slightly different point of view than others on this forum. <br><br>A few years ago, my local branch of the Recreational Aircraft Association (similar to the EAA, we're a bunch of home-builders) was looking for potential topics of interest for our monthly meeting guest speakers. I suggested to the co-ordinator that a lecture on Wilderness Survival in the event of an off-airport landing would be of interest; he responded "Okay, I'll put you down for June." And hey presto, I was an "instant expert" ;-)<br><br>One of the criticisms I got at that lecture was when I showed my own "survival kit", which at that time fit inside a large Ziplock Freezer Bag (IIRC). The response was "I fly a homebuilt, I barely have enough room for an overnight bag, let alone all that stuff." I have since found out that the majority of people can't be bothered to keep a survival manual in their glove compartment, let alone carry a PSK when they're hiking in a Provincial or National Park. (I wonder if the fact that they're in a 'Park' gives them a sense of false confidence?) <br><br>So I personally would prefer to have a PSK that is small enough to fit in my shirt or jacket pocket and let me forget about it, with a larger SK in my backpack. I figure the SAS Pocket Guide in one jacket pocket, the Altoids tin in another, and a Survival blanket in my shirt pocket *should* be enough to see me through most nights.
