What may work to bring fans west would be a format somewhat like when the Manzanita race was one week end and Ascot the next. Maybe something the same but more compact.
The cool thing back then was you could go to Pheonix see some things, race then sight see In Los Angeles then race again.

Probably hard in this day and age for fans to get a week and a half off, or pay that much for that long of a stay.

Maybe something like Race Monday-Tuesday, Off Wednesday and Thursday, then Race Friday and Saturday.
