Dean:
You might try this "Blag" tactic...Talk to the editor of your local newspaper, could be a weekly, and tell them that you are going to Goodwood (build it up...show the clip) and that you would like to give them an exclusive (pictures and story line) for the Local Interest section. If they are interested, you'll need American Press credentials along with the others in your party. Then you'll have to deliver, but your inside.
Give it a try. It doesn't cost them anything. They may say "Yes" Exclusive, no other local paper will have the story and they might tie in some advertisment from local Foreign Auto services firms...incremental $$$
Good luck.
