DUBLIN, IRELAND - St. Patrick's Day festivities are happening all over the world today.
In Dublin, Ireland, more than 500,000 people have lined the two-mile route of the St. Patrick's Day parade.
This year, Ireland is pushing itself especially hard as a tourist destination, as the country faces its worst economic struggle since the Great Depression.
Tucson's St. Patrick's Day parade and festival was last Sunday at Armory Park.
