Mom gets from that magazine. And when I saw the latest issue I knew it was gonna get Mom's wheels turning. When Greg's mom decides the family are going to have an 'authentic experience' this summer on a family road trip, Greg is less than excited. All the Heffley's trapped in a minivan for miles and miles... it spells disaster. And when Greg has to battle petrol-station bathrooms, crazed seagulls, a fender bender and a runaway pig, it seems he was right to be worried. This is one adventure the Heffleys won't forget!
