The bicycle is his harbinger. Sammy flies the American flag from a three-foot stick duct-taped to his rear basket. We see that flag and know he’s coming. Both the rear and front baskets are interlaced with red, silver, and blue tinsel. By day the baskets may hold lawn-care tools or groceries. At night, they’re filled with flowers. Sammy is unimposing: few inches shy of six feet, not an ounce of spare flesh on him. He has the sinewy muscle common to laborers, endurance athletes, or users. Leathery dark skin taut over his sharp cheekbones and jaw, teeth set in a slight underbite. Weatherworn fingers, and bony, like they could lick fire from a harmonica.
