[Exile on Spencer St]

Thanks for such a thorough summary, Macca.
As a non-combatant, it seems to me that one key to help unlock this could be the earlier suggestion that HBC are in discussions with LCC to 'acquire' the land west of the playing fields in order to turn that into public open space.
If that happened it may answer those who claim it's the loss of access to 'public' land that is the issue.
Alternatively, it could be helpful if LCC could support the proposal and make its (i.e. 'your) surplus land available, so the Trust doesn't need to use all of Higham's.
