I believe there are times when it seems like they do live everywhere. I also know they are like other birds, animals, or even people. It doesn't matter if you build a new burger shack a few hundred yards from whataburger and it may be called watsonburger, I know its different and im going to go with the proven winner 90% of the time but 10% of the time whataburger may have to long a line and you can catch me on french fry in a new brush pile.
