I have mentioned before that when it rains for any length of time, a river runs through our yard. The water drains from our neighbor's yard, across our driveway, through our yard and into the road. It has created a large washed out section in our front yard. This exposed area of red clay is the kids' new favorite place to play by digging in dirt and making a big mess. We need to figure out a good way to divert the water away from our yard. Any suggestions?
