That might be the perception, but wrestling is popular on both coasts and in Texas atm, it seems to be floundering in the South. Vegas provided TNA with much better crowds, but they never do house shows there or in CA to my knowledge. I'm sure a west coast house show tour with decent advertising would attrack more than 200 fucking people.
Not sure how much it WOULD help, but you're right. TNA has to try something.
