Mexico City Flag Ceremony
Every day, at 6 AM and 6 PM, soldiers and military police converge upon Mexico City's Zocalo to raise the flag (morning) and lower the flag (evening). Though the tradition isn't as widely known as the changing of the guard at Arlington National Cemetery or Buckingham Palace, it's equally impressive and worth a visit.
