Bhumibol Adulyadej, the King of Thailand, left Siriraj Hospital for an extended time for the first time since 2009 on Thursday. He and his wife, Queen Sirikit, who is also in the hospital, went to the Royal palace in Hua Hin, a seaside community about three hours from Bangkok. Thousands of people lined the road near the hospital hoping to catch a glimpse of their revered King.
