This old tree has been trying to find space in the sidewalk. Its roots have curled into themselves. It fights for space with the concrete walk, the underground pipes and the pavement on the road. And yet it still thrives. I often marvel at how nature finds its way, with weeds growing in the tiniest cracks and trees taking root on their own wherever they can. We need to treasure our trees - nature's natural air conditioners as their shade cools and their breath gives us the oxygen we need.
