What is an Expedition? An expedition suggests a journey or excursion by foot [Greek word "pedi"] undertaken for a specific purpose. The word was often used in connection with a military objective: "an expedition against an enemy stronghold".
Fundamentals of a successful expedition
The basic requirements for a successful expedition are food, water, shelter, and a meticulously maintained vehicle. Although there is a great deal more, without proper attention to the above, the rest is really irrelevant.
