Wallace take a cruise - Pollan flirt with grow opium poppy - Darcy Frey hang with a young Stephon Marbury and friend - DeLillo 's `` Pafko at the Wall '' - the devastating critique of the McMartin child abuse case  at a buck a issue , it only take a few brilliant piece such as these to make this magazine worthwhile .
