We were lucky that it was even offered at my HS (public high school). I decided to take it my senior year since I'd already had 2yrs of Spanish (French or Spanish was required).
I enjoyed Latin quite a bit, but I admit, I don't remember a whole lot. I believe it was very helpful anyway. As others have said, it does help translate or just figure out other latin-based foreign languages.
In college, I took 2 semesters of French (again, it became a requirement to take a language). Am I dating myself?? :P
So...I'm a dabbler in many, but a master of none.
A lot of you gals make me nervous...especially the educators on here! I know I must murder the English language at times. Hopefully I am not making you gals cringe at every post. 
My fav Latin phrase: Quod me nutruit, me destruit.
