Ali-
Please don't give up. I have had days where they didn't work so good too. I don't do rivers much so I'd don't know how much the current could be a factor. On lakes anyway, it is a rare day I can't at least catch a few. Ask those boys how they were working them the day before. It sounds like they had them figured out. My only idea would be to try slower & smaller. Maybe cast up into the current to slow it down.
You can get a cheap disposable digital camera at Walmart. Then you could get pics & still release 'em for another day.
