Mark of the Crew

Right beside my leaf pile, I stumbled on a fat, broken stub of yellow sidewalk chalk rolled against the railing! I didn't hesitate—I gripped the powdery block with both hands and dropped all my weight right onto the concrete. SKRRRRCH! The rough stone bit deep, kicking up a bright yellow dust cloud! I marched backward, dragging the blunt tip in giant sweeping loops to sketch an enormous grinning pirate skull right across the grey slab. The crossed bones came out crooked as anything, but our official crew mark is blazing under the porch light for anyone who dares approach!
