Re: what am I doing wrong
Well, a bit more info would help. First question I have, how long have you been fly fishing? Also, were you swinging the nymphs, fishing them on a dead drift? Patterns you were using, did you have any takes at all, or no activity? Could be a million and one things going on there to be honest. But if you try to give me a bit more background I'd be glad to offer up some advice from my meager experience!
