My encounter today at Manada was awful. There were 2 guys who were upstream of Carlson bridge and they took issue with me being in "their" hole when I was in fact downstream of the bridge opposite side of creek. Also my buddy had rocks thrown at him yesterday.
I did not have my phone on me unfortunately. They were trying to be verbally intimidating. I approached the hole quietly from downstream. Fish couldn't see me. If anything they would be spooked from the slobs upstream. I said it's trout season on a popular hole in a very popular stream. Second day to boot. I asked if they were they're yesterday and the guys said don't talk to me. I saw 1 or 2 of the vehicles they drove. One is a tan or goldish Tahoe from late 90s to early 2000s. Other is a red ranger with a cap and a small sticker on the tailgate.
Sounds like you took the high road and in the long run you are better of for it. It stinks that this happened and you can bet these bums with big mouths that are the same bums found in bars looking for trouble. I wonder if they would have been so confrontational had you not been alone.
Opening weekend always brings out the best in people. Sometimes it's hard to take the high road and keep your mouth shut, but in today's world you just never know. No fish or spot is worth fighting over.
I'm thinking from your post you're a young guy with a lot of common sense. You'll run into some bone heads once in awhile. By not getting into it with them shows you are a lot more mature than they are. Good going.
