3rd night = Wishes from Main Street. Everyone has a favorite spot and mine changes depending on whether or not the park stays open after the fireworks and whether you plan to stick around afterward. With a young group, I'm guessing you'll want to go to bed after the show (and that's a pretty good way to end the night).
A military coup (d'etat) is an organized action by the armed forces of a country meant to overthrow and replace its government.
The military has a mirade of abbreviations. The abbreviations are what indicates the organization of the military, and the exact place that a military unit or even an individual played within in. Unfortunately, these abbreviations are so much gobbledegook to many people.
