But cannot see Gospel Oak! (doesnt mean it is not there!)
So many stations seem to have reference to TREE !
Arnos Grove / Oakwood / Wood Green / Colliers Wood / Royal Oak / Burnt Oak / Woodside Park / Wood Green / Becontree / Theydon Bois / Elm Park ..... to name but a few!!!!!
My favourite is Hornchurch (A golden horn tree is native to Northern China !!!!! Church is FOR preachers
Parsons Green (got the preachers, but it is stretching to make Green a Tree?
St John's Wood - Got the tree and St John (no idea if it is St John The Baptist) was no doubt a preacher
My favourite is Hornchurch !!
