The annual display of the U.S. Capitol Christmas tree is a popular attraction. But it's also a bit sad that one of the nation's oldest is felled for a month of work on the West Front Lawn. It wasn't always this way. Back in 1963, a 24-foot Douglas fir was planted, but a bad storm and root damage killed it five years later. Since 1970, the "People's Tree" has been selected from different states. So why not try a live tree again? Officials say root damage from the crowd-crushing July 4 concerts and inaugurations spells certain death.
