When our bull gets out, he often heads over to the septic system. (Our fence wasn't made for a bull in mind, but it will be beefed up soon.) This is where the grass is the greenest right now. The septic drains into the valley where two hills meet, which is naturally greener from extra water runoff from the hills. With the extra septic outflow, however, it is really lush.
Tonight while I was tucking the kids in, I went to close their curtain. Their window faces the septic system, and I happened to notice 9 deer feeding there. It must be a popular spot. I just hope that our bull doesn't get too jealous and think he needs to go protect his spot!
