Don't be mad at the game warden. You were the irresponsible one that didn't look into what you needed before you went.
not to rub salt in the wound, but this is right. and take it in perspective: in the big scheme of things, it's small. but i bet you never make that mistake again.
that being said, i know someone that got the same ticket as you and took it all the way to the parish court, and wound up paying an extra $100 on top of the fine because of "court costs" that were assessed since he actually showed up for his hearing in court. make the phone calls and pay it in advance. this is my advice.
