I knew you were going to Washington, D.C. :)
I have not been since age 5 -- twice in my lifetime seems reasonable.
I've been 5 times, only twice as an adult (I think, can't recall - was very close several other times, but don't think I went all the way in), and never during cherry blossoms. That was on my life list, but will probably have to be forgotten now. *sigh*
