The announcer called the adult contestants to the line and I had that first guilty tingle – similar to what the Roman plebeians must have felt when they watched the lions pacing back and forth in the coliseum, waiting for dinner to be served. The drivers skidded through the watered-down infield to the start. Engines in need of lozenges roared. The announcer counted down. The green flag waved and seconds later my senses were overwhelmed by the endorphin rush from hearing the first metal-on-metal collision.
