The beginning of the Lewis and Clark expedition ( a very long journey that one takes seeking something). They had to get across the west on their feet, because they did not have very good technology (the application of scientific knowledge for practical purposes, especially in industry).
It's time to start our journey looking for a route to the Pacific.
They had to fight up the Mississippi river in canoes.
We are not getting anywhere fighting up stream.
Best of thanks, lets get to our boat.
I know the land. I can help you find your way.
They met an Native American women (Sacajawea) that helped them in their journey.
They had to hunt for all their food.
They also had to sleep outside by a a camp fire if they were lucky.
Well I guess there is no route to the Pacific, considering that we are at the Pacific side of the land. It is time to head home lads.
