Summer or winter, I love walking in the rain for hours, just outside in the rain jacket on. I hear the sound of the rain when it touches the trees, It's soothing. An other fun thing is when birds talk in the trees during rain. I notice so much energy and excitement in their sounds. I also say hi to them. The natural aura and fragrance of trees, grass, and soul enhances my spirit.
The best fun thing is if you have tea or coffee in a flask in your backpack. I usually find some bench or a log anywhere I am in the rain. Drinking coffee out in the small rain is immense pleasure. Or tea as well. You come home so refreshed and happy having spent time in pure nature.
