Slingshot and Burp—two pea-shootin', slingshot-totin' cowhands on two wheels—are on the lookout for action. Bleached bones? Bring 'em on! Lost outlaws? Let's go! Hidden loot? Yee haw! Rattlesnakes! Scorpions! Ghost cats!Wait, what . . . ? Whoa! Saddled up to battle the boredom of summer, these two double cousins, best friends, and next-door neighbors have fitted themselves out like Old West cowboys to charge boldly (and sometimes bravely) into the southwestern desert that is their backyard. And sure enough, in two rattles of a snake's tail, the boys find themselves boots-deep in adventure, dodging sisters, jail time, coyotes, and squirting skulls! Boll weevil!
