Book excerpt: Join Mark Witas as he skateboards down Sprague Hill, barely escapes the whirling terror of the formidable rapid Satan's Eyeball, paints the neighborhood pets with his friends, and dangles 20 feet from the top of a 70-foot cliff with nowhere to go. His adventurous spirit, engaging sense of humor, and relevant life applications will have you sitting on the edge of your seat day after day.
