I'm not answering any more questions, because, honestly, after taking the time to answer what I thought were specific questions specifically, directly and correctly, I was blown right past and saw that all the OP really wants is another fucking fest. We have enough of those and why bother, only to be ignored?
I say stay where you are and change the laws in your state. Far better use of resources and time, and it will affect a far greater sphere of influence.
I'm in some agreement regarding perception of this issue with delae. I've never spent time in Colorado except connecting through Denver, but I do get the impression from many online personas, here and elsewhere, of "Don't come here!" It's just a perception. But then, perception is reality.
I think that we, as a group, are far more accustomed to huge influxes of people than folks in Colorado may be. However, there are those places that are exceptions to that 'rule,' and I think many, if not most of the rural and ranching areas of the state qualify. It is through these areas that Proposition 8 passed, and where the consensus against another particular group has much the same flavor ("illegal" aliens). Just start up a conversation in my county about them and you'll soon hear bitching about them taking their jobs. Yet, last year we had a shortage of workers who were actually willing to work! Watch the cost of that food skyrocket, too, as farmers have to work harder to get workers who'll WORK (cuz 'mericans ain't them).
Again, this is my perception.
