Y'all Come Back Now, Y'Hear?
The Time Traveler Convention, May 7, 2005, 10:00pm EDT (08 May 2005 02:00:00 UTC), East Campus Courtyard, MIT, 42:21:36.025°N, 71:05:16.332°W, (42.360007,-071.087870 in decimal degrees). MIT wants to publicize the event, so that all future chrononauts will know to gather in the quad.
Personally, I subscribe to the notion that time travel will never be invented. The reasons have nothing to do with physics or technology. It goes like this: If time travel is technically possible, and if it is possible for a traveler from the future to change the past, and if said change can alter the traveler's own future, then time travelers will keep screwing with the past until the come up with a future where time travel is never invented. Other assumptions require either someone/something enforcing a no-paradox rule, or infinitely branching universes, which offends my sense of economy. But it is well known I'm cheap.
