A word of caution for those of you installing ground anchors in campgrounds for use as dog tethers. If there are underground utilities/services (electrical, water, irrigation, etc) there is a strong likelihood that your anchor could hit one of those services. If it is electrical, you could be fried. If water, you could get wet and have an unexpected shower.
