Inside the massive expanse of Ho-b RC Park, certain echoing sounds are constant. The blow of a starting horn. The whir of miniature wheels on the carpeted track. The intermittent thud of an RC car taking a turn too sharply. These sounds let visitors know that a race is underway, where drivers by proxy stand atop a block overlooking the racetrack and thread their scaled-down cars through tight curves and long straightaways. Post-race, drivers can peruse the shop for new vehicles, replacement parts, and aftermarket decals branded by miniature detergent companies.
