You should be prepared for going into the outdoors even if is for less than a day.

• Make sure you know the area you are going to ahead of time even if it is just looking at maps.
• Check the weather.
• Tell some one you trust where you are going and for how long. If you are going some where with a park service tell them too.
• Make sure the people going with you are prepared.
• Know some first aid and read this wikibook.
• Talk to some one who has been where you are going or has more experience, better yet invite them along.
• Make sure you keep your car in good condition for car trips.
• Bring a survival kit.
• Go with at least one person if you can.
• Practice survival skills. Practicing them can be lots of fun.

If an emergency happens relax, prioritize, and be creative with what you have.
