kfk, The DNR did nothing to stop the evasive species from being here in the first place. Now that they're here and spreading, this is their attempt to slow it down. I am not against educating boat owners about how they can help do that. It's the way they want to do it. If you're pulling a boat and the drain plug has been removed, trailer is free of weeds, etc., they have no reason to pull you over, period. The majority of people know the laws and abide by them. The time and expense used on this could be better spent on researce to find ways to remove or eradicate the invasive species now here. (I see "muscles" in my original post should be "mussels"...)
