Some folks over at MIT are holding a time travel convention. The idea goes that there would only ever need to be one, because people could just turn up from whatever time they were in.
It's on at the east campus courtyard MIT, May 8, 2005 02:00:00 UTC.
I have no plans to go right now, but I will definitely consider going sometime in the future if it transpires that I can.
So, I might see you there!
Come to think of it, I might see me there as well...
