Getting Ready For Winter

Fall, many things represnet fall to me. The leaves change color, from bright green, into yello, burnt orange, red, and finally brown, where they end up on the ground. I hear the dead leaves crunching under my feet, while I am walking to my mail box. At my apartments, we have a huge oak tree. It is shape shifting into his winter mode, where it will be barren until spring. The great oak, must be about a hundred years old. This morning, I saw a squirrel burying nuts underneath it's trunk, getting ready for winter... I don't know how squirrels do it, burying nuts, and then patting the ground until it is hard to tell where they bury them, and then finding them during the winter months. How do they do that? It's a truly amazing thing to watch...
