Just a quick visit to this one as I was passing the area. I was inapropriatly dressed for a full explore so just a couple of surface shots. The post is basically at the side of the road although completely hidden by a farm enclosure. The hatch has been ripped open and is badly damaged and would not close looking down the shaft it appears that rubbish has been dumped down there car wheels etc. It is also very wet. anyway the pictures.
If you want a closer look down the shaft the large image can be viewed here: Sleaford ROC Post 5
