My vision is to be prepared as best as possible. While no one can prepare for everything that may or may not happen, one can be somewhat prepared. The basics such as some food, water (this is a critical item) and while we can only hope it never gets to this point, guns and ammo. If things get real bad, people will turn on you in a heart beat to get what you have. You can have food & water supplies to last for years, but if you can not keep it, you are doomed.
Now if an asteroid hits the earth then all bets are off and none of us may make it. But at least have some type of plan and vision for the future. Good luck to all!
