A Google search for "salmon fishing leader" or "drift fishing leader" comes up with most of the answers to your very simple question. And why are you playing the phone directory like a piano? Larry? why not call curt or Ron or some other random biologist too Maybe they'd know. ..

Or you could just call a LEO in a district that will be writing these tickets, like for the skok maybe try Smith or Juet.

I don't think fly guys are part of the issue here so I doubt the regs are really looking at them. The rule was gonna be 20" min. And 48" max but this is what is out...flossing will be harder, the bump and rip crowd will probably line more fish in the head and mouth...and us real fishermen will have some more spots open to just us as well as the BEGINNING of what might be a turning point in these type of fisheries (one can hope).
