A worldwide trend has locked onto Des Moines and won’t let go. Remember the “love locks” that had Paris all atwitter? Visitors to the City of Love have long pledged their undying devotion by affixing padlocks to fencing on a bridge over the Seine. Locks bear appropriately poetic inscriptions, such as “Sophie + Burt” or “E loves C,” within or without an encircling heart shape. By the thousands! Paris overcame its romanticism when the density of lockage turned the fences into walls of steel. With some romantic despair and no ceremony, city crews unlocked all that love and pitched it — sentiment and shackles, all cast asunder.
