About as close to ten miles each way as you can get, though I never get the same distance twice, it seems. I rode in and out five days the week after I put a computer on my Rivendell Road, and when I rolled into the garage on Friday afternoon, the odo read exactly 100 miles. It's mostly on side roads, with a few dangerous crossings, some glass-strewn shoulders (passing beneath the interstate on a busy six-lane "street") and about 300 yards of grassy "trail."
The place in my commute where I've most often come the closest to being hit is, believe it or not, the crossing I _walk_ my bike across -- with the "WALK" sign, no less. Sheesh!
