I've just been reading through the sale guide for 2012 in this week's Scottish Farmer. I'm a bit disappointed but not altogether surprised to see that there are fewer RB sales this year.
Thainstone has two - 5th May and 1st September
Caledonian, Stirling doesn't have any listed, neither does UA, but then they've never done one. The Caley one was the annual Heb Show and Sale too, I think.
Carlisle has their big sale in September 22nd.
Dingwall - 10th March and 3rd November
Even Lanark doesn't have any listed. It does have regular poultry sales though - as does Forfar.
Were they just not supported?
