I'm not sure what you have read. I pretty much thought people were just chiming in where they'd like to see a Rally. As far as I am concerned, if the Rally is held in Colorado as has been suggested a few times, it's fine. I just don't know that it would work out for me. If there are enough people that WILL support a west location and show up, then by all means.
Why not?
However, as Steve and Phantom have mentioned, their ability to handle the minutia of setting up a west location may or may not be feasible.
