The invisible faculty.

I had departed the medical school much too late to reach this small Georgia town before dark. Most of the 175-mile drive south was in daylight on interstate highways, but traveling the final 57 miles after nightfall on unfamiliar secondary roads was a challenge to my sense of direction. I arrived safely at my motel at nearly 9:30 p.m., fatigued from a long day of clinical work and meetings and my decision to fit this daily medicine clerkship teaching site visit into an already over booked schedule. After a brief review of the next day's meeting itinerary, I got some much-needed sleep.
