Robbo in all of that you said basicly what everyone else has said "traffic congestion is here to stay so learn to live with it".On the surface runoff you said the best system would only get 80% of the noxious material which would be nice since there's virtualy no systems anywhere in the state.I believe Bellvue was building one but don't know if it's done yet.Personaly I believe pollution is the biggest hurdle in fish recovery,if you were a fish it would be like sitting in your garage with the car running and the garage door closed. That cabin livin would be nice but I don't think the wife would go for it.
