I came upon this magnificent old elm tree on my annual Canadian bike ride (this year Prince Edward Island). Because of their hardiness, elm trees once lined most streets in every American town and city, then sadly over time (between the 1930s and 60s) they succumbed to Dutch elm disease. So far this solitary elm tree has escaped the disease thanks to a prevention program and perhaps the fact that it stands alone. We should all plant a tree for posterity!
