Officials with the Kentucky Derby Festival say clear skies Firday and Saturday should help make up for several says of rain and floods.High waters have already forced relocations for several festival events. Spokesperson Mark Shallcross says fortunately, the Ohio River is receding now, as the busiest week of the festival begins."The weather's not predicted to be bad this weekend, because this is one of our key weekends with the mini and the marathon and the balloon events. We're just trying to stay positive," he says. "We think people have sort of cabin fever after all this rain and cloudiness and flooding."Rain is expected on Sunday. Shallcross says the effect of rain on attendance to events over the last week hasn't yet been calculated.
