I am glad to hear this "police state" is going away. Just because you see out-of-state plates doesn't mean the person isn't paying their fair share. It would likely be a wash if the assessor's office hired someone. Once you hire someone, pay their salary, benefits, health insurance, retirement, etc it wouldn't recoup enough to justify the position. Even if you did it would create a circumstance where people would be spying on their neighbors.
People can comment all they want but, the decisions have already been made. It's all about the money. The best solution is to do nothing. Let the river run. Find and punish violators. But then you wouldn't have a bloated bureaucracy asking for more money every year. Just like the watershed, self-sustaining semi-government.
