i like the air... it has a certain crispness.. not unlike winter.. but with a smell... i know this sounds weird.. but early morning rides down by the lakeshore, the fall air is filled with smells of wet leaves, mud, lake water, and even a dash of worms.
those smells make me think of the impending snow storms and i ride faster along the trails.. knowing that i can ride that morning
i don't care if its damp or cool.. because after a long ride.. i can go home, mellowed out, ready for work that day.
