I am SO thankful for underground sprinkler systems! I have never had good luck with the cool ones. You know, the high ones that go back and forth that the kids get to run through. They'd just stick in one place and not go anywhere no matter how expensive sprinklers I would buy. I'm sure they make for prettier pictures, too. But, all in all, I will just sit here and be thankful. This is my sprinkler shot. I put my camera on the ground, and shot. Pretty decent..
