With a population of less than 100, Leopold is the site of a Roman Catholic church, St. Augustine; a general store, Guillaume's Store; a restaurant, Marcy's; and a quiet atmosphere reminiscent of another time. On the last Sunday in July, Leopold holds its annual St. Augustine's picnic, which serves both as a fundraiser for the local parish and as a homecoming for former residents.
