I live in a state with unlicensed open carry, and Shall Issue concealed carry permits with zero training requirements. I've not seen anyone open carry, though I have seen a couple people who had some sort of hybrid carry going on where it could have been a careless version of either.
When gun laws have been suggested or raised in the Statehouse, we've had demonstrators with people slinging a rifle over their shoulder or walking around with a drop-leg but that's pretty rare, and not carrying for carrying's sake. Likewise I have seen a guy wearing a western rig and a single action colt, but it was blackpowder, unloaded, un-capped, and for a halloween costume. Again not something I'd label as open carry for carry's sake.
Maybe the training requirement adds up to more people open carrying, but I doubt it. Even our demonstrators out here are a fairly small band when they come out at all. For being a "blue state" full of "liberals" our gun laws are just too good to rock the boat.
