An estuary, I believe, is part of a river rather than part of the sea.
We have been the closest FL club to the Mersey, apart from a short 11 year hiccup, since Hermann Goering's raid on New Brighton FC's ground in 1942.
Shame he did not order a slight diversion to Prenton Park, Anfield and Goodison at the same time.
Of course, OT copped it in 1941. The Luftwaffe also targeted Maine Road, but when they saw the state of Moss Side, they thought someone had already beaten them to it.
