Uncharted Radius

I opened up my throttle across the open expanse of painted concrete, breaking away from the safety grooves to test my full cornering speed. With no rails to confine my bogies, I banked hard into the open floor. My plastic wheels broke traction on the slick gray surface, sending me into a controlled, silent skid. I carved a wide, sweeping arc around the base of the yellow handrail stanchion, trailing two clean, swooping lines through the fine floor dust. Leaning into the centrifugal slide, I let my motor hum at top pitch before easing into a smooth, deliberate spin-stop. Behind me lay a complete, flawless circle.
