That sucks. I am originally from PA and it was confusing at first as to what was open and fishable and what was not. I had vacation the 2nd week of Apr. my first year here and almost went to Macedonia on a picnic and to fish. If I hadn't checked the book I would have definately been screwed.
If the book isn't out then you may have a very legitimate defense, although I suspect that the response will be something like ignorance is not innocence.

Good luck.
