We have 50, plus one smart arse...
Figured it out by myself, but don't appreciate your being an arse.
Sorry, I didn't mean for it to come off like that. I did not mean to imply what you infer, as Barry Farber says. To atone for my sin, the web site of the Military District of Washington, the wonderful men and women who managed this week's honors, covers this in their
Origins of the 21 Gun Salute page. FRegards.
