Nice photos preceding, chaps. Tightest I can ever remember was at
Out Skerries in Shetland Islands at, officially IIRC, 381m. Took an Archer in many years ago. It
was a bit tight, not least because it is far from flat and the takeoff run available depended on how large a boulder you were prepared to trample at the easternmost shore end !
Dunno if it has been tarmaced yet ... ?
