I have come to expect this kind of behavior on Peninsula rivers. I am not sure where you were but I fish the Hoh very frequently...and sadly this is a common experience. Last year I lent my boat to a friend who is a competent oarsmen and knowledgable fisherman. He beat a guide to the put in, firstwatered him about halfway through the drift and then pulled ashore to let the guide pass by and have his own first water.

Pretty noble of him I'd say...

When the guide caught up to him he said some very nasty things about my friend's female passenger, insinuated he was poaching and mentioned that "he'd heard gunshots" and "my friend better watch out because it was dangerous downriver".

We laugh about it in retrospect...all the scrawny little man was capable of was bluster....

I see him out there all the time,I am sure he knows my boat...the back of it anyway.

Best thing you can do is be extremely patient and if you are inclined towards vengeance, beat them at their own game. Beat them to the takeout, outfish them...respectfully and silently.
