I found another one ..

... without really looking for it.
Some time ago now we experienced the "Winter Droving" 
One of the spin-offs seems to have been an epidemic of Strange signs which, I think, may have been mentioned elsewhen/elsewhere.
Both of us having been Lurgi-Ridden of late we kept the necessary perambulations to a minimum, but it didn't stop us being forced along certain no traffic paths. In one of which I spotted this one.
Cue for a song?
