I'm sure I could look it up and research it, but in some regards if someone wants to take the time, lots of people would benefi from this......I couldn't tell you the difference in the field between a RIO, Eastern or Merriams. Other than local, what are some appreciable differences. I've heard some tlak buff this or color........
I run alot in the Methow and in the Coville. I'd bet I run into Rios and Merriams or even mixed but couldn't tell you one from the other.
