I once found a chap collapsed on the Isabel Trail, just on the cemetery side of the Eccleshall Road bridge. I decided that it was probably a 'substance' issue, but he couldn't be left where he was, so I rang 999 and selected 'ambulance'.
The dispatcher was happy with my assessment and wanted a postcode for my location, which I was unable to give, even if there was one. I carefully described it as being on the
disused railway line running under the A5013 in Stafford cemetery. I laboured the point about it being disused, assuming he might be looking at a map to locate the scene. Despite my best efforts to dissuade him, he became convinced that I was on the main line under the bridge in Great Bridgeford and was on the verge of shutting down the rail traffic when I managed to remember the name of Izaak Walton Street as a suggested access route.
Anyway, a chap from a car turned up, via the cemetery, assessed things, agreed that the bloke needed a lift and arranged for that, then left me to 'supervise' the service-user and his bags of kit, as he went off to guide the pair with the full-size vehicle to scene via the alley off Izaak Walton Street..
