Offering advice, attempting to "educate" others, w/out asking em, I think is bad manners. Maybe that's how momma raised me, but seriously, why go up to someone and offer unsolicited advice or "educate" them about fishing, rules, etc. unless they ask? Couple years ago I was fishing taney with a new flyrod, reel, line, etc. All new stuff. And I was minding my own business, and god forbid, watching my backcast! Some self-appointed flyfishing instructor walked over and told me I shouldn't watch my backcast and proceeded to tell me (I've been flyfishing for 20 years) how to properly cast. You know what, sometimes I like to watch my backcast, especially when I'm unfamiliar with the rod and not only want to feel it load, but want to watch it as well. I was ticked that someone interrupted me and acted as though I was a novice. I probably could teach Lefty Kreh a thing or two about flyfishing ya know? I didn't say anything rude, I just said I meant to watch my backcast cause I had a new rod. I've had a lot of anglers ask me for advice on the stream and I'll freely give it, often with a fly or two to boot, if that's what they's biting. But I'd never just up and approach someone and start "educating" them. Ain't right, and could get you a punch in the mouth too. No matter your good intentions, what your telling that person is they are wrong and you are right (and smarter, more rightous, etc.)
I've never responded more to a thread than this one, guess it just touched a nerve, and yes, I've had more than my share of stream encounters with know-it-alls. I swear, they seek me out! When fishing, man, I just want to do my thing and be totally left alone. i do my best to ignore everyone else. I wouldn't even fish Taney 'cept darn it, there are some nice trout in there! I swear I'll never fish there again after tangling with the crowds, then I'll hear about a state record brown being caught on a size 16 scud, and I'm back again...
