Pinfold Lane, Retford - anyone know it? Guy stuck

Chap has posted on a facebook group i'm part of saying he is stuck on Pinfold Lane in Retford - anyone know it? Is it a legit lane and open? Not suggesting LZIR should go out, i don't know if the chap is a member and don't know him so can't vouch for him in anyway, just wanted to know the legality of the situation. However, if anyone local is interested I can put you in touch with him.

Know it well .. it's a dead-end, closed at the North end by a locked railway crossing. Well known by local Mudslingers and with very bad (Tractor) ruts. If anyone wants to go tug him out they'll want lockers, extreme tyres and a decent winch ..

It _is_ legal, but not an advisable lane for a solo drive at all.
