After the Vietnam War re-enactment, there were other things going on.
Like I said earlier, they had planned to have the Thuderbirds this year but the Thunderbirds and Blue Angels were cancelled because of the sequestration. And this was because Congress can't do it's job. Yes, they can say that it is the President's job to propose a budget it is ultimately their job to pass it. I hope that the Blue Angels and Thunderbirds are back next year...but I'm not counting on it.
