Oregon is generally legal, however cities and counties can make ordinances against those WITHOUT a CHL. I consider them a "licensed open carry state" for this reason.
Washington has a stupid law called RCW 9.41.270, and the Seattle area PD's have a hardon for threatening open carriers. Even in Eastern Washington this is a problem, see Fishorman's fiasco.
Florida, open carry is illegal unless you're carrying in a way that would be legal to CCW without a permit, like your own home or to and from a hunting trip. With the new self defense law just passed, there's probably going to be some effort to make Florida's Concealed Weapon or Concealed Firearm license law into a Concealed Weapon or Firearm License law, in that your CWFL exempts you from the open carry provisions, specifically to protect people from accidental exposure of their guns. That's the reason why TN passed a "Handgun Carry Permit" law.
