On May 7th, MIT is holding a Time Travelers convention and all are welcome. Though students are lightly hoping that someone from the future might arrive with a cure for cancer (John Titor where are you? [and incidentally, where's that civil war that's supposed to hit sometime this year?]), it still looks to be a great time regardless. Students are hoping to get a few professors to speak on time travel, and most party-goers are planning on dressing the part.

The gathering will be held at 42:21:36.025°N, 71:05:16.332°W for those with time machines requiring specific coordinates; for others, it's at MIT's East Campus Courtyard. Also, according to grad student Amal Dorai, if you want to help get notice of it out to party-goers in the future, "write the details down on a piece of acid-free paper, and slip them into obscure books in academic libraries," or "carve them into a clay tablet." Maybe John Titor will pick you up on his way.
