At this point it may well be too late to pull the Expo but it's probably in it's death throes anyway as the industry morphs into ever more commoditization. I was planning one final visit as I'm pretty much done in business with retirement an attractive option at the end of this year. Not worth my time/risk now.
On a seperate issue: Dissapointing to see that this industry also has its societal % of conspiracy theorists and raving nutbags. Take care out there.
