I've been dipping in out out of the Hipper for a while looking for a spot that Vicar took a pic of a while ago http://www.flickr.com/photos/thevicardrains/5090443554/
Every few months I'll be driving past and dip in for a look, I still haven't found that one but I have found quite a few others...
Well I was heading home and realised I'd never seen the Chesterfield Tunnel even though I posted the lead on it well over a year ago
Access was a nightmare with the footpath next to the wall and fence being the busiest bit of path I've ever seen
Eventually I just jumped over and almost broke...
