Well, they won't pay your way BUT you will get the following:
All the free food you can handle and its good!
A very nice hat that is not available to the general public.
A very nice golf shirt that is also not available to the general public.
And most important are these two factors: first, you WILL get a seat that money cannot buy and you will be helping assure the safety of the greatest motorcycle racers on the planet.
How can you beat that?
