This was a hole.
The gas company was looking for a leak, and eventually found it under the first patch. But a couple of months later, a sinkhole developed for some reason in the same area. (According to my old friend and engineer, Donald Mosshart, they didn't pack the soil right). You can see the patch over the sinkhole, and you can also see that another sinkhole is developing.
Be thankful that the road crews aren't working as your chiropractor - simply band aiding the problem and letting it recur. Your Rockford Chiropractor believes in getting the foundation set right, so you don't have to keep fixing the "sinkholes" that develop.
So, no matter what you are dealing with - headaches, autoimmune disorders, pain syndromes, ask yourself if the original problem is being corrected.
