I wonder just how different the two flavours will be. I mean yes, obviously there will be differences and some will be major, but both states are going to have the same essential elements: the same terrain in places, the same native Americans on the land who may cause trouble (admittedly the level of tension and warfare with these is likely to be one of the defining features). But I don't wonder if, in the early days at least, the idea of Sheriffs, posses, bandit gangs and shootouts won't be fairly similar both sides of the border - not to mention that there's not that much about being an actual cowboy that can change with which side of the border you live on, so when cowboys become idolised and mythified when the frontier becomes "safe" (whenever that is for both states) presumably both countries will have the same phenomenon of important or affluent persons travelling to spend a year as a cowboy and experience the life. If we think about the spaghetti western films, it could be that a Magnificent Seven type film wouldn't really be produced any differently by Southern or Northern Americans.
Of course, I am open to correction, and I'd be very interested to hear just what factors there are which will be different.
