Thanks, Ken -- you know you're welcome any time, even if you don't happen to bring any corn salsa. :)
I don't think the actual track will need a slope as steep as the picture shows, but it's planned to rise one foot every five or six horizontal feet after Eau Rouge. It's a pretty serious hill, so getting Eau Rouge just right will be critical for a decent lap time. Eau Rouge is going to be squeezed, so drivers will have to be smart!
