Anyone who has driven into town has surely noticed the sign declaring that Swarthmore is “Tree City USA.” Naïvely, I always assumed we were THE Tree City, but it turns out that there are more than 3,400 of them across the country, and 115 in Pennsylvania, that have met the exacting standards of the Arbor Day Foundation. We’ve decided to poll our readers to select Swarthmore’s Favorite Tree, as nominated by a panel of experts. We urge you to see as many of the candidate trees as you can before voting.
