I don't know if anybody's covered this yet, but Sportsbook.com has just signed on with Walker to be Manning's primary sponsor. (They are also the presenting sponsor for the Miami race).
Sportsbook.com is a London-based online gambling company. But whatever happened to Air China? They came on to replace RAC. Three different primaries in the same season!
Good news for Walker, Manning, and CART in general.
