Yeah it just totally and utterly disorientates you,no landmarks or nothing..I was out last season with Darcy when the pea souper rolled in,we totally lost our bearings,infact we thought we were heading close to an airport as we could hear what we thought were aircraft the noise was even surreal..As we trudged on we eventually came to a small embankment & a f***ing Eddie Stobart lorry sailed past!! No airplanes at all lol,couldn't hear a car passing even at 20 yards!! Darcy walked 6 miles up the road dodging death on the narrow grass verge with vehicles having very little visibility to say
