It is all gone. All the guns, all the ammo, all the magazines. Many of the stores in Prescott are a boarded up and posted closed.
This is a critical lesson to everyone. In the time of actual emergency, supplies will be immediately wiped out. Water will be gone from the shelves, food will be gone. Ammo and guns will be sold out.
Being prepared to provide for you and your family starts well in advance of an emergency. A year ago, you could buy a bakers dozen of AK47s for $400 each.
This is not an end-of-the-world perspective or some stupid zombie outlook. It is a reality. Katrina, Sandy, etc. all happened. Economic collapse has happened. Prepare for it with a few months of food and some bulk water storage. Coordinate with people you trust to ensure that the stores are protected. Then stop thinking about it.
