Are you going? I hope you have a report for us if you do. I seem to recall having a chance to go when I was in Toronto way back in '99. My gf at the time heard about it but said she couldnt justify spending $15 (I think?) just to walk in the door. Probably for the best - I would had sensory overload!
I go under the theory that since COMC is there to accept dropoffs, admission is cheaper than actually mailing them in. Anything else is a bonus!
