Ordered them from
http://www.gpfrancemoto.com/ They are an officially linked to the Le Mans circuit. Tickets were supposed to begin to be mailed out after 6/4/2005. Looks like I will be firing an e-mail to them for Monday.
From some previous posts there are a number of members/posters who are going to Le mans but no official DSC trip. Having organised this trip for 7, I would not like to take on organising one for a large group.
