Randy, the spaces out west can be so vast, you could almost make an argument that most every state have its own 'region'. For example, it can take as long for me to drive to the top of AZ from Tucson as to get to San Diego!
That being said, I don't think you have to 'go Texan' and break out each for now, but I would be much more inclined to travel to Phoenix 90" away for an event than say, NV, 8 hours driving, and the board probably should reflect that reality
Perfection is reached, not when there is no longer anything to add, but when there is no longer anything to take away.
