Before retiring over a year ago, my commute was 14 miles one way (28 miles round trip).
It was mostly flat except where I crossed over other roads via overpasses. My route included city roads, rural country roads and streets that wound through neighborhoods.
In the winter I would start out in the dark in the morning and just barely make it back home before it got dark in the evening. I loved the morning darkness ride.....very little traffic was out....I raced the sun going home....it wasn't a nice place to be in the dark at 5:00 or 5:15 in the afternoon or so. All the war wagons were racing to get home from work!!
We've relocated to another state since then. I really miss that commute.

Some day when I begin my second career maybe I'll be fortunate enough to be able to commute again.
