The things I always have with me are a good Sebenza and a good attiude. My little possibilities bag is about 3x4x6 and has the usual compass, water purification tablets, fire tools, signal mirror and whistle, nylon line and thread, fishing hooks and lures, 100' monofiliment, 6x12 plastic sheet and a Nimravus cub. The leatherman wave and a water resistant wind suit ride in my flight bag or daypack depending on the senario. Of course water and food are always somewhere in my kit along with a water filter and a digital camera.
