Don't post too often but now is the time we all come together.
I echo the statements of others here and say if you haven't been down to the ground then I implore you to do so. It really does show how someone who you probably have never met can have sure a positive and profound impact on so many people. I was in shock at the number of people down there today, and the number of tributes is breath taking.
Even if you don't have anything to lay in rememeberence, please go down, it might not hit you now, but in the future you will look back and be glad you said thanks and goodbye.
