My favorite stimulus project occurred on the Tulalip Reservation where my buddy tells me they put sidewalks in very low traffic residential areas where nobody really wanted them. Then, a couple of weeks later, tore the sidewalks they had just put in out and put them back in slightly different. Not sure why they had to tear them out or who screwed up and more than doubled the cost by requiring the tear out/re-do. At least there are no roundabouts there....yet.
