Skunked again. This place sucks most if thime. I wonder if it is ever stocked like the say. I drive over an hour for a fish empty lake. Even the locals are complaining. I need to go on Thursday morning to witness that in fact fish are making it in. For $25 for fishing and parking, it's a bit of a rip off to get skunked. Home friday will be worth it...
