Mark your calendars. Someone is planning to present a 3-day convention next year, celebrating the 30th anniversary of John Carpenter's original version of HALLOWEEN.
Dates are August 29 through 31, 2008. The exact location is not yet named.
The official website is here. It contains little information at the moment, but you can sign up for a newsletter that will update you with details about guests, etc, as they become available.
