St James were able to use St Joseph's old ground and Letham had an unusually good setup for an amateur club regardless of the knockback from the EoS, so who else has access to something similar this time around? Breadalbane do and get mentioned on here whenever this subject crops up but then don't actually apply.
Can't think of anyone else with a suitable ground (Stobswell and Osborne's old ground is now a cemetry and a second coming for Bankfoot, Alyth, Errol, Balbeggie or Crieff Earngrove seems unlikely) so that basically makes Luncarty, Jeanfield, Kinnoull and Montrose Roselea the prime suspects to put the old Tayside regional setup back together again but they may be happy where they are.
