OUR 2021 CONFERENCE will bring us to Durango, Colorado, my hometown near the very southwestern corner of the state at the edge of the mighty San Juan Range of the Rockies and the high desert plateaus of Utah, New Mexico, and Arizona. My own route here was a circuitous one from the U.S. South to northern Europe, to the western U.S. to the northeastern U.S. and back again to the Rockies. Durango combines a few parts of all of my favorite places though, of course, its seas are long gone and have left very different impressions in the landscape.
