(DC) (Casey Trees) Join Casey Trees with Tree Ambassador Glenn Hall for a Tree Walk at Oxon Run! We’ll start off with an easy-paced tree walk, where Glenn will give an overview of the history of Oxon Run Park and then point out some of the species of trees in the park, and finally go over the importance of green spaces such as Oxon Run Park. If you want to learn more about trees and love spending time outdoors, join Casey Trees on Sunday, November12th for this unique event.
