I did it for 6 years, and I enjoyed it very much (although couldn't get those damn verbs in my head, to much alike). We learned it very passively, not having to build Latin sentences ourselves, but rather enjoying and analyzing those magnificent texts. Cicero's In Catilinam was amazing, I enjoyed the battle epics, the love stories, the historics.
I had really fun teachers who were passionate about the language and the Roman culture, which helps alot of course to motivate pupils.
The active knowledge is gone I guess, but it build the base and structure in my head for every time I encountered a language since then.
ignore their patronizing
tear off their blindfold
open their eyes
