Every trade show ebbs and flows with the economy. I have gone to the Consumer Electronics Show from 1980, and that show went from crazy highs to ultra depressing lows. Golf shows are no different, and the economy doesn't discriminate at all in industries tied to consumer demand.
Given some of the zest that is in the golf industry now; young stars, great colorful fashions, new technology.... I'm sure the show has some new bounce in it's step.
