The Blue Runway

I squeezed through the cracked porch door and bolted straight onto the concrete patio! Resting beside a mossy flowerpot was a chunky cylinder of bright blue sidewalk chalk. I planted my back paws, leaned my chest against the blunt edge, and shoved forward with all my might! Squeak-scritch! It skated across the rough gray slab, leaving behind a bold, electric-blue zigzag track. The gritty sound made my ears twitch with thrill! I lined up at the beginning of my new runway, took three rapid hops, and slid belly-first along the line, kicking up a tiny puff of bright blue powder!
