urgent dispatch, the scent of the road

The 5 senses - sight, smell, taste, touch and hearing - we could probably write a little essay about each one and how we experience it on tour. Right now, though, I'm thinking about smells of the road, of gasoline, farms, factories, exhaust, tea tree oil, gum, cologne, sweat, slaughterhouses, trees, fresh mountain air, greasy diners and topical analgesics - it goes on and on. I never really thought about it until right now, but touring the country is sort of a tour of the nose.
