For those of you who enjoy delving into interesting maritime information, challenge your knowledge with one of the 50+ quizzes on naval trivia/history, etc. at: http://www.funtrivia.com.
It's free! You don't have to be a member. And you're likely at the age when you NEED to keep your mind nimble! Just log in as a guest, and type "navy trivia" in the quiz search box.
