We live in uncertain times with constant threats knocking at our doors. One day, we might live under Martial law and although the use of Martial law should bring an end to the scenario that imposed it, most of the times it will lead to further violence and chaos. The United States, like many other nations has a long history when it comes to Martial law and some fear it may soon be upon us. The current scenarios that foresee Martial law are all related to ISIS attacks that could happen on US soil. This is why you need to have a survival strategy for when Martial law hits.
Bartering should not be a skill forgotten in ancient past or used when you try to bring down the price of cheap, vacation souvenirs. Trading goods for goods or goods for services might someday become a need in our modern society due to its vulnerability to economic collapse.
