I don't know how up to date these odds are, but according to the web site, the current future odds for the Las Vegas Hilton put Colonel John at 7/2... and Big Brown at 6-1! I find that surprising.
Some of the other odds are pathetically low.. Court Vision & Cowboy Cal at 12-1... Smooth Air 15-1... Visionaire 20-1... those horses will be higher than that on Derby Day...
