Roger,
Not sure where I heard or read this but seems as there was a reason to give the mouth of the Fraiser River a wide birth. I belive it had to do with high flow rates and considerable sediment in the river run off water causing abnormal engine overheating. I do remember going buy there on a ferry one time and noticing the obvious difference in water colors.
Hope you have a neat trip. PLI is beautiful. Enjoy,
Harvey
