The About-Face

Interbike is returning to Vegas, after announcing it will leave it's traditional location for Anaheim. This turnaround strikes me as odd...isn't moving a gigantic, week-long event hard to do less than a year out? Wouldn't moving it back cause even more hassles? Interbike is a division of Nielsen Expositions (kinda the way that seemingly innocuous beverage companies, like Snapple, are owned by Pepsi Co or Coca-Cola or Disney), and they're saying that they got a "very real response that surveys and discussions alone couldn't accomplish." What is going on here?
