These discussions never cease to amaze me.
Here we are, in the best place on Earth, with the cheapest fishing licenses in the world, yet some people look to cheap out on a steelhead tag, the proceedings of which are mostly spent on the enhancement of the very activity they are buying a license for.
If it so important to save 25 bucks a year on a hobby they claim to be so passionate about, maybe they should change hobbies and try...I don't know...birdwatching.
Just buy both tags and be done with it.
Gives you peace of mind and helps enhance the fishery.
