I go camping a lot and sometimes I am ... genuinely sad to come home. There's a certain pain that comes with modern life in the city that's absent in the wilderness. The longing for the wilderness becomes a creeping desire - a desire that will start to haunt you when you do things like ride the bus (that's always late and too crowded), or fight for a decent wifi connection at a coffee shop. You'll pick up some fish at Whole Foods to cook and think about what you caught, and ate, the previous weekend - and when you eat what you bought it just isn't the same.
