ST. CHARLES, Minn. – When the good Catholics of St. Charles Borromeo Parish chose a knoll just out of town for a new church, an attraction was the bucolic setting. Such a calming and fitting backdrop for worship for a town seeped in its agricultural roots. Less so now. Beyond the parking lot a vast solar array has been installed and intrudes on the site’s original pastoral purity. Look carefully, though. Corn still grows in the back Back 40.
