KRUGMAN GIVES UP: Don't worry,Paul Krugman! Once you accept the Hobo Jungle as an inevitability, you can start to plan your life there. And it's still early. There are many spacious trash mounds left to stake out -- some real steals. Get one near a sewer! You can fish for your own rats, which will be both the preferred food and currency within the Hobo Jungle. [ Paul Krugman ]
