Tree culturist P. G. Cross thinks we should all get up-close and personal with trees: "If you would live life in all its richness, then make friends with your trees, your neighbor's trees, the trees of the hillside and the highway. To form such a friendship means serenity of being, better health, and above all, lasting happiness. No tree ever proves to be a false friend." Befriend a tree for the summer. Look out for its welfare. Notice its moods. Sit beside it and bask in its energy.
