I quoted a member of the NSW kayak club some time back. In essence, he said to pre plan,prepare with the best possible gear and finally never,ever take a trip based on having the equipment alone. The best of us can become just lax enough to invite trouble. I have my PSK, so Ill take that ill advised hike and then fall off a cliff in spite of my photon 2 shining it's heart out. No Altoid tin can replace common sense or forthought.
