I don't know what it is about dirt and little boys, but the two are nearly inseparable in our household. We had a little spot in our grass that hadn't quite filled in yet, and now I know that it probably never will. As soon as it started to feel like spring (in February!), the boys were out with their diggers, shovels, and other tools. The little grass-less mound was soon flattened and every trace of grass growing on it was gone. These boys sat out here for two days straight, working on their site. I'm not exactly sure what they were doing for two days, but they enjoyed themselves! Nick even rigged up a spotlight for them at night so they could continue to work after dinner.
It was also a great time to snap some photos of them since they were occupied in one spot with some decent lighting.
