Activists supporting the inter-Korean summit between South Korean President Roh Moo-hyun and North Korean leader Kim Jong-il wave South Korea's national flags, as they wait for Roh in a motorcade toward North Korea, near the presidential Blue House in Seoul October 2, 2007. Roh takes a historic step across the heavily armed border with communist North Korea on Tuesday for only their second summit, billed as a chance to bring peace to the divided peninsula.
