I definitely agree with RAS on this one.
I remember my first camping trip all too well, a friend and I brought in several 2-liter bottles of water, food, tent, axe, rifle, sleeping bags, etc... and this was only for a 1 night trip about 3 miles from my home.
Growing up "in the woods" so to speak, I was very comfortable using an axe or a rifle. The rifle was more of a backup in case of rabid animals. To an untrained person, however, a rifle can be a liability as you would often try to shoot an agressive animal as opposed to trying to avoid it.
Back to my main point, you want equipment with you. No one should knowingly put themselves in harms way without proper survival surplies. The whole point of Doug's site is to be prepared. If you carry even the most basic of survival equipment with you, you stand a greater chance of surviving if things go wrong. With that knowledge, why would anyone venture into the woods with almost nothing in the way of gear?
If you want to experiment with survival skills, do so, but only in a safe manner. As RAS suggested, try making a figure 4 trap, see if you can catch supper. Go fishing with just line and hooks. Try setting snares. And, if you catch something, see how difficult it really can be to skin and prepare. Try to start a fire using flint and tinder you find in the woods. But always have backup!
Make sure you have adequate fire starting tools / matches / lighters. As an Assistant Scoutmaster for the Boy Scouts, I'm often amazed at the inability of some scouts to start and build a proper fire. This is a skill that is crucial for any sort of outdoors experience.
Make sure to carry a proper knife and multitool. Have enough water with you, but carry a way to treat / boil water if you need to, or to show how it's done. Bring along food, properly sealed. Nothing worse than running into a bear that has been attracted by the scent of food left lying around. (Trust me, I've seen this in a boy scout camp! Luckily the scout was not hurt too badly!)
As the scout motto says, "Be prepared!"
And for God's sake, please let people know exactly where you will be, how long you will be away, and when to notify SAR if you don't return. You state you will only be 1 km away? Bring proper communication equipment. Even commercial talk-abouts (walkie talkies) should work for that short range. But test for that distance before relying on it.
To sum it up, bring plenty and enough equipment to surive for longer than you plan on being there, just in case. You don't have to include it in any shots. Don't be silly and try to eat plants you are not sure about. As many have said in this forum, food is not critical, but water is!
Come back safe!
