Dundee is the safest Yes area in Scotland.
Angus could go either way. I've never understood how some of the area are so massively SNP area especially around the suburbs of Dundee (Monifeith and Sidlaw area) where most people are old.
Edinburgh's not bad. Encounter folk with Yes badges whilst walking in the street most days. I've always got a badge on myself so it's good when we give a wee head-nod in acknowledgement.
