From near Nashville Tennessee through North Alabama and Mississippi to the Louisiana border there exists a 444-mile roadway called the Natchez Trace Parkway. The only signage you will see is related to non-commercial scenic viewpoints. No billboards. No businesses. Nothing but forests and fresh air. Furthermore, no commercial traffic is allowed whatsoever on the full length of the byway, and the authorities strictly enforce that rule.

It’s glorious. Waterfalls, walking and biking trails, Indian mounds, and miles and miles of advertising-free roadway.

That project management triangle is an example of a trilemma.
