Iceland and the United States celebrate Leif Erikson Day. The Viking may have discovered North America in the year 1000. Idea: Children could research the evidence and decide which European found the Americas first. October 9 has no association to Erikson; the date was picked because the first ship filled with Norwegian immigrants landed on October 9, 1825. The day was first recognized by Lyndon Baines Johnson in 1964. Every president since then has honored the day. Some people believe we should honor Leif Erikson Day rather than Columbus Day.
