Newport County used to play at Somerton Park before going all nomadic.
Maidstone sold theirs and ground shared.
Council bought The Shay in the late 80's and it's leased back I think.
Darlington FC and 1883 - that's a messy one, Feethams was sold and that new stadium was a disaster.
Chester City had the Deva, and Chester FC still do - not sure if they own it.
Scarborough City didn't have the McCain Stadium, it was flogged to Lidl.
AFC Rushden and Diamonds played at the Dog and Duck with Wellingboro.
Hereford still play at Edgar Street.
74 Northwich groundshare with Winsford, Vics still play (in the same league as 74) - but they are at Witton Albion. The Victoria Stadium was another disaster. Incidentally, the Dane Bank terracing at Vics Stadium was bought by FC United, and is used in the St.Mary's Road End.
