This is just like what has happened to "Cruising" with your car in towns across America. Cannot do it anymore. If you are caught coming and going more than one time on the same street you get busted, because that means you are causing trouble. No parking or loitering on the sides anymore, that means you are causing trouble. No parking in the vacant lots adjacent to the streets showing off your bitchin ride, that means you are causing trouble.
Same thing with the channel. Because there is a minority causing trouble, the rest of us "normal" people are scorned for it. I think they need to take a different approach to the problem.
And if that is NOT the reason for a fee, but intead they are just looking at ways to create revenue, maybe they should look into the outrageous wages some officials are making.
