Rugged Tree

Going sideways a bit is this ol', big rugged tree. The first tree I can ever recall was one outside the kitchen window on Washington Avenue. I think it might have been a mountain ash. I was only about 4 or 5, but I  knew for sure it was a tree and not a bush. It was covered with hard orange berries that hung around even through the winter and provided food for the birds. It would have been a fine place to hang one of my birdfeeders too. Close by a large window, it would have been a wonderful viewing location to watch the winter action of 'attacking' the berries. I remember one time, out alone, I managed to wiggle and climb up about 3 feet off the ground. What a sense of accomplishment! I thought I was so high up. I had reached the point where I could peer into the kitchen and see Mom. She was some surprised, threw up her hands and raced outside to 'save' her precious one from imminent disaster.
 By the way, do you think that type of tree is a mountain ash? I still don't know.
