Be a good neighbor! Don't flood your neighbor's cook site with your grey water.
It's amazing how often this happens! People don't think about the slope of the ground. At our last competition my wife went to pick up a 12-pack of beer that was stashed under our trailer so it was out of the way and the bottom fell out of it. It was soaked by grey water from our slightly uphill neighbor! Then we had to clean up spilled beer and broken glass!
