Most laws like the Zebra law that is not only not enforceable but stupid. It is not about the spread of Zebras, it is about a lot of stupid stuff coming from politicians, money. If I let my lower unit down for 10 minutes and then pick it up and go home. When I get home I let it down to park my boat and water runs out. Water is in my carpet, water lines to my live wells, where do these people come from. Was at Texoma driving around there is water coming over and threw the dam everywhere. Every lake below Texoma, Ray Roberts and any other lake below them will have mussels in it before long. It is not how they affect the fishing or people that put there boats in and out. It is about the pipelines and peoples boats that they leave in Marinas. Like I said at first, its about the money. We need to learn to live with them or figure out how to get rid of them. I have seen several post where fish eat them. Not seen it yet, but I hope too.
