Poop: It's not usually something I spend my time thinking about, unless of course I'm having to change a diaper, or I'm on the Stairmaster and realize my sneaker is covered in dog shit. Then I think about how gross it is. Recently, however, I was standing down by the Willamette at Cathedral Park, staring off into space thinking about boys or shopping or nuclear attack, when I noticed one of those "Danger Sewage" signs..
