Rolling through GUAYNABO, Puerto Rico (CNN) - Sen. Hillary Clinton's marathon caravan through the communities surrounding San Juan rolls on.
For the last several hours, the candidate has stood atop a souped-up white truck with her campaign logo splashed on the side. She's endured drizzle (umbrella immediately appeared) and sun (visor put on).
She's blown air-kisses to the crowd, waved at women in rollers who have come running, screaming, from beauty parlors, and stood quietly looking out over the landscape.
The mess of reporters following her has had the chance to survey every change in her facial expression as they hang off a covered truck mere feet from the presidential candidate.
The never-ending, ear-splitting soundtrack for this Puerto Rican campaign tradition is a mix of Ricky Martin and a salsa campaign jingle that includes an announcer screaming, "Who is here? Hillary Clinton, the next president of the United States!"
At various intersections, drivers of trucks and cars lay on their horns, trying to compete with the decibel level of the roughly 15-foot speaker leading Clintons ever-growing caravan.
As for news? It's slim pickings. One intrepid pool reporter attempted a question about the DNC meeting that could decide the status of disputed delegates from Florida and Michigan as the candidate briefly ducked into a restaurant but came up empty.
The caravan - over 15 cars long - rolls on.
