Rumours have turned into more or less believable financial figures recently how F1 could take Long Beach back. These mills include some investors you might have thought of or you had wished you have. From the race fan's perspective that doesn't really matter. What matters is whether the so-fragile organisation of IndyCar could survive yet another such loss.
Make no mistake here, Indianapolis + Long Beach = IndyCar. The rest of the season can be replaced with other contenders. These two races define what IndyCar is today. American open-wheel racing once lost Indianapolis to a rival that is running IndyCar today, and it wasn't too far off to say the definite host of The Great American Race would hold the 500-miler with stock cars. During this period it was up to Long Beach to fly the flag for CART and it is fair to say that it forever established itself as the "street Indy" apart from being the "Monaco of the US" [insert your rant about it here]. Either of these races go away during such unstable period for motor racing, IndyCar shall be driven to the ground now, most likely.
