The smell of cattle before the storm.

This will be short. The smell of cattle dung seems to be the harbinger of a storm. I don't completely understand this but it smells like cattle before it storms in Denver. I asked the staff at the restaurant where I ate at about 6pm tonight, "why does it smell like a stable tonight?" They remarked that every time they expect snow in Denver it smells like a horse or cattle stable because the prevailing winds bring the smell of rural Colorado or a Purina processing plant into Downtown area. Weather experts predict 6 inches of snow to Denver tonight. Wow. What a travel fact. It smells like the Minnesota State Fair here, and it has started to snow.
