Walter G. Tarrow, aka “The Subterranean” columnist on Townbroadcast, made a trip to Grand Valley State University Monday with his wife, Janet, to get a look at “The Sweetheart Tree” on the bridge in the middle of the GVSU campus. Walter, in a fit of pique 51 years ago, carved a heart on a tree on the bridge near Padnos Hall, declaring his undying love for this then-girlfriend. The couple earlier this month celebrated their 50th wedding anniversary and the carved heart remains, but the “Walt + Janet” inscription is no longer visible.
