Sorry, not as inspiring as some people's stories, but here's mine:
My commute to my part time job is 9 miles uphill. I have to go on a path, several arterial roads, two smaller roads and to save about 2 miles I pick up my bike and hop a railroad track. And I do this at rush hour, as I work a 5:30-close shift. I've done it in the rain and with a heat index of 124 (although the actual temp was only about 104f)
