How did Thomas Jefferson convince the people that it was a good idea to move to the West Coast?

From his earliest years as a political leader, Thomas Jefferson believed that America's future depended on westward expansion.  His greatest accomplishment to that goal and the action that greatly encouraged westward expansion was the Louisiana Purchase.  In 1803, against his own reservations, due to it implications on anti-federalist ideology, Jefferson purchased over 500 million acres of land from the French.  He paid $.04 per acre for the land. Jefferson immediately organized the Corps of Discovery to explore the new purchase and chart the future of the United States.  This expedition was led by Meriwether Lewis and William Clark.  Jefferson believed that liberty depended on private ownership of land and the small farm was the quintessential representation of freedom.  For this reason, he implored Americans to move west and settle in the new lands acquired by the Louisiana Purchase.
