Chalk Marks the Spot

Trick shots were crushed, so I needed an official field boundary! I stomped away from the clay pot and ducked right under the wooden balcony bench. Hidden in a dry shadow was a tiny nub of faded blue sidewalk chalk! Score! I clamped both blocky hands around the dusty stone, planted my feet on the rough grey tile, and shoved forward with all my weight! Skrrrrt-crunch! A thick blue zigzag stripe carved straight across the concrete, marking our club's supreme agility obstacle line! Let the tryouts begin!
