The retired IBM exec decided his town of Cheswold, Del., needed something big for a tourist attraction.
So, he's built what could be the world's biggest pumpkin carriage.
While he's grown 400-pounders in the past, Caldwell decided to construct his big orange ride out of fiberglass.
The 7-foot-tall pumpkin carriage carries up to eight passengers and even has hydraulic brakes.
He says he's contacted the Guinness people to see if his pumpkin carriage sets a new record.
