Here is a crude drawing of the course layout for you....
View attachment 249664
Green line is the start/finish....I'm not positive but I think it had to pick your car up through both lanes to count the lap.
Red Lines are jumps
Red and Gray line is the "table top" jump
It isn't to scale or anything but hopefully putting it together with the pictures give you a better idea. The garage door with the plywood in front of it and the man door beside it would be at the long sweeping corner on the right end of this diagram.
