Hmmm.  Not so sure I agree with you since many have been here since a very young age.  Is somebody who spent the majority of their lives in Colorado NOT a Coloradoan?  I am a Colorado native but I am sure many friends would consider themselves a Coloradoan since they have lived here a majority of their lives (as opposed to say, California or Texas or Wyoming or Kansas, etc.).  Maybe we are both nit-picking.
