I was going to mention that. That's the reason I have felt Laguna doesn't deserve a Moto GP race, I never felt Laguna did anything for it, it was Roberts, and now Red Bull .I don't think many realize that the USGPs at Laguna in the early 90's were all financed by Roberts himself. He did what he had to do to be sure there was a GP in America.
Well, they did add the T3-T5 section for GP. And they also re-did the areas around the Corkscrew. But I do get your point. And, if I understand correctly, it's more of a park than a full on commercial venture as a racetrack. I'm sure that also plays into their willingness, or not, to promote an event there.
