abstraction. war is real, with real consequences. >> and tomorrow night, the national mall will be packed with people honoring our war heroes at the annual memorial day concert. a lot of people come on motorcycles. a friend of the military gary sinise will co-host. sinise has been doing uso tours with the lieutenant dan band, which we all know from the very famous movie, he's been doing that for years since his oscar nominated role in "forrest gump." he started the foundation to bring even more support to the troops. he joins me now live from washington. gary, it is such an incredible thing that you do every single year, and all these veterans who come out, it's almost hard to describe the feeling on the mall of all these people coming together. what is it about it that just gives you that kind of hope, that fire to do this? >> oh, it's a remarkable event. good afternoon. this is my tenth year here for the national memorial day
