Rice For Peace, a not-so-new idea in non-violent protest of war.
Long story; short pier notes that the anecdote of Eisenhower being influenced by a similar campaign in 1954 to decide against bombing China is an urban legend. The Fellowship of Reconciliation issued a message last week to clarify the use of the anecdote in promoting the Rice for Peace campaign. Doesn't mean it's not a cool idea, though.
(If you do choose to participate, please note the packaging alert, which was the first thing I thought of when I read about sending baggies of rice to the White House.)
