I Read this article in the current Field and Stream issue. Its a new concept (at least to me) that seems pretty controversial. Almost sound like the fish is being lined but then again its not because the fish did strike the hookless fly. The article says that they tried it steelheading on a Lake Erie trib but doesnt say which state, and yes, I know what it says in the Ohio regs under snagging so no need to quote it. Anyway I sent it to ODOW to see how they would interpret this method with the law. Ill post their answer as soon as I receive it.
