We hop on a bicycle made for two and daringly try to navigate through the city. Amsterdam, famous for its tulips, hosts the biggest flower show. We discover the true story of the boy with his thumb in the dyke, and get to sample a little snert. But we also see reminders of a time when tolerance could not be taken for granted. Ho Chi Minh City, or Saigon as it is still called by people who live here, has been familiar to many westerners since the Vietnam War. The underground tunnels once used by the Viet Cong to launch surprise attacks on the Americans are now a tourist attraction, but they serve as a reminder of a gruesome war.
