This weekend at the Massachusetts Institute of Technology there will be a major Time Traveller Convention at the East Campus Courtyard. As far as I know, this will be the first such convention of its kind, but as the press release states given the some possible natures of Time Travel there really need be only one such event. Though, if too many travellers arrive there could be space issues, unless mastery of time travel includes mastery of space occupancy.
Naturally, the one thing quintessential to the success of this event is in advertising and not mere internet advertising. After all, if some major cataclism should occur between now and the advent of time travel any internet communication would be lost. We need to create and ensure a significant fossil record and fill space with radio waves containing information about this event.
Come on everyone! Let's promote this baby!
