I, of course, have no way of knowing, officially. However, if crowded roads have anything to do with ticket sales, I would say that they are holding up pretty good. I had the misfortune of going up I-29 from Kansas City shortly after the end of the Kansas race this year, and it was bumper to bumper, two abreast all the way into Iowa/ Nebraska. Wendy's on the Nebraska/Iowa line was full of sunburned people wearing "their hero's" logo tee-shirts. Also, my daughter lives in sight of the Texas motor speedway, and commented that everything in the area beginning on Friday of race-week was jammed up(roads, shopping malls, etc.).
