Imo, you should be able to target at least 1 city in all 50 states. I don't travel so I don't know if places like Montana, Idaho and Iowa have the infrastructure (stadiums) to support a PPV, but if they do, it'd be foolish for the WWE to not target that town at least once a handful of years.
Towns like New York, Chicago, Seattle, Portland, Baltimore, Boston, Philly etc etc don't deserve a major PPV because they're in an area that may get bad weather is wild to me. To say towns like Charlotte, Nashville, Jacksonville, Houston/Dallas, Milwaukee, Detroit, Phoenix etc etc don't deserve one doesn't compute.
I'm not saying drag a PPV show to every state capital...but I also think you're fooling yourself if you don't believe the hope of catching a big show in your town doesn't attract more fans.
