you could also try kinmount estate at annan , its also a coursing estate and onec held the annual scottish cup , they have been culling them there too and i know they were involved in moving hares several years ago , not sure if the hares were broughgt in or shipped out but they will be a good source
there used to be several hares in every field at kinmount , but you hardly see them now there a rare sight there nowadays
