Can't read that link for some reason Peter.
I remember Mablethorpe. Just north of Skegness. Worked there at Butlins just before I sloped off to Leeds in the early 60's. Suspect housing there is in the doldrums also.
Where's Mapleton ? I was born in Hornsea...which suffered bad coastal erosion when I was a kid.
Mapleton's been on the edge for years. It Always used to be on Calendar & Look North when I was a kid. Completely forgot about it TBH. I seem to recall a main road was closed with a huge crack in it & later ended up in the sea!
