Jerry, I dont know you, but having read all this I feel I need to comment.

You say you have never ever heard about any CCGTCC trade session?
There have been a number of sessions at EVERY convention.
Apart from the fact that if you have your old show catalogs as you say, then you would see them listed in the schedules, the convention timetable including those trade sessions is posted every year, and has already been posted here/linked to, several times, for this year.

For info, here is another link to it:
