Wagah, an one in only Army outpost on Indo-Pak border - between Amritsar and Lahore, is an elaborate complex of buildings, roads and barriers on both sides. The daily highlight is the evening "Beating the Retreat" ceremony. Soldiers from both countries march in perfect drill, going through the steps of bringing down their respective national flags. As the sun goes down, nationalistic fervour rises and lights are switched on marking the end of the day amidst thunderous applause.
