The Sefferer Conference 2012 was a conference for the people who saw (or think they saw) an alien. It was named after Sir Jonathan Turner Sefferey, who was the first (reported) member of the British Parliament to have seen a U.F.O.. He was reported to have seen it on April 1st, 1674.
What is the Seffery Conference, you ask? I'm afraid I can't blatantly give you that information as it is to remain confidential by orders of the government of Mars. I can, however, give you this brochure to help you understand the magic of Disneyworld. Go have yourself a good time.
The Seffery Conference is a secret MSL (Mixed Sport League) that specializes in the game of hockeyball (a mixture of hockey, soccer, rugby, football, badminton, tennis, croquet, track, archery, swimming, and illegal street racing(both cars and motorcycles)).
