Just a very quick point for you all to consider, an I am sure Bob and Doc will fill you all in as we go. There is a huge concern over parity, non-guided verses guided. The Board of Fish wants it to be virtually equal and they don't want to limit or make it difficult for the non-guided angler to participate in the fishery.
As far as the oil in the river it is obviously from 2-strokes. The days it got into the dangerous zone were on Sundays. This day there are not guide boats on the river, only civilian boats. Most of those boats are older and the majority are 2 strokes. My guess is 95% or higher of the guides have 4 strokes. The problem is not with guides and their motors.
