Several almost unimaginable events have caused air travel in the United States to be cancelled today and there is no word on when air travel may resume.

Tuesday is usually the travel day for racers, teams and the sanctioning body.

AMA sources say that if air travel does not resume by the end of the week, it may be fairly difficult to have an event, even if 90% of the series participants are based within driving distance of Willow Springs.

It's wait and see on a lot of different levels right now in this country.
