Indeed, it is a sombre day. A day to reflect on the great courage and patriotism of not only men and women of the Armed services who paid the ultimate price serving their Country, but the brave emergency services officers who fought to save lives in tragedies like 9/11. When I visit the States in the future, I plan on visiting Arlington National Cemetery and the National September 11 memorial in NY. I would encourage everyone else who is able to do the same atleast once in their life. Similarly I recommend visiting the National War Memorial in Canberra if you ever come to Australia.
