I purchased my ticket to the Northeast Conference on Science an Skepticism in late August and hadn’t received a ticket via mail yet so I contacted the event coordinator and promptly received a response:
Your ticket was mailed on September 2nd and you should have received them. If you like, I can add you to the VIP guest list with a convention pass waiting for you when you arrive.
Wow, VIP list? How awesome would that be? Some fat guy wearing a “Stand Back: I’m going to Try Science” shirt with a VIP pass busting through doors or with a lab coat replying to “why are back here?” with “that’s a stupid question”. Nothing bad could come from this. Or better, I could bring my big-un camera and people would confuse me for someone with skill. I might not even look for the tickets.
