I think a great idea would be for the NTRA to do a pick six pick 6's wager for a dime. in order to hit it you must sweep the pick 6's at six different tracks. it would be sooooooo hard!!! but!! when someone hits it!!
They had a $1 60 minute Pick 6 at 4 different tracks this summer (Belmont/Saratoga, Delaware, Monmouth, Philadelphia) and it was a fantastic bet and generally a success.
