This was the question on my mind, is biking not an option in Detroit?

I bike to and back from work daily 14 mile round trip using a cheap 2nd hand city bicycle. Snow and cold only makes it more fun.

Of course, I am lucky that I am doing it by a choice and could take the bus or drive my car.

His round trip would be 46 miles.

For me, there's some sort of qualitative difference in a bike ride that goes over something like 10 miles, so I can see why it isn't a first thought for a 23 mile trip.

No his round trip is 23 miles.

I can't possibly fathom why your first thought to travel 23 miles would be to walk? Biking is OBVIOUSLY so much faster, easier, less straining, etc.

Getting to and from his factory job 23 miles away in Rochester Hills, he'll take a bus partway there and partway home. And he'll also walk an astounding 21 miles

He walks about 3.5 miles, takes a bus to the edge of its service area, and then walks another 7 miles to the job.

I meant to write 21 miles (not 23 miles) round trip:

"Detroiter James Robertson, 56, walks about 21 miles a day"

So he would only have to bike 21 miles per day.
