I smell the willows growing along the Mississippi River on the flood side of the levee. Willows (and cottonwoods) smell different to me than other trees - more of a musty smell.

BEER! The levee path goes under two graineries.

There's a funny smell that sometimes drifts over from the shipyards where a Navy ship is currently under construction. Not really a paint smell, not sure what it is - I can see them welding. Does welding metal give off a smell?
