Marc DeSouza has an email list of people that he emails when lectures come to his house. If you have never been to Marc's its definately a treat.
His whole basement is magic. Wall-to-wall-to-ceiling shelves with magic books and notes. A whole room of magic apperatus, and a beautiful lecture theater.
His lecture theater has tiered seating, approx. 30 seats which are real reclining movie theater seats with cup holders and everything. The view of the lecturer at the front of the room is exceptional because of the tiered seating you are looking slightly down at the lecturer (you can see the cards on the table).
I sent you an email on how to get in touch with Marc.
