Urban survival and wilderness survival are a lot alike and at the same time worlds apart. With both you need survival skills and the right tools to do the job. At times the tools are the same for both kinds of survival. But your needs in each area are very different. Like water in the wilderness you can find water in many places, but in an urban environment water may be a very hard thing to come by or you may find it and it's just not safe to drink. You must prepare for the area you are in and near because you may have to bug out to a area near by. Make plans to survive in both the urban environment and wilderness. Lets say you live in the city and you have always lived in the city. So you plan for a urban survival situation, you have water, food and shelter and ways to replace any of the need supplies you have, but you don't have a back up plan for an emergency bug out to the wilderness that is near your area. You never have even been to the woods for more than a day hike. And then you find yourself in the heart of the woods with no plan and very little supplies and no wilderness skills. Your chance for survival has dropped off the chart. I live in a rural/urban area it's close to a small city and very close to the wilderness so I plan to survive in both areas. I have both urban and rural skills, although I'm not even close to being as ready as I would like to be. I still make plans and work out any problems I find. I add to my preps and as time and money allows I add needed tools and equipment for survival in both urban and rural areas.
Make your plans to fit your area of survival, and stock up on the needed items. Our time is short and with each day we draw closer to collapse. So do what you need to do to prepare and store as much food, water and other supplies as you can for the coming Dark Age. Our way of life and the way we live are about to change forever. Be ready for it so you can survive.
