Yep afraid we Scotpeeps have this one covered

), we were below minus 20 earlier in the week, and not a one-off, we were last winter as well.....:-o We are not far from Braemar
tbh once you get below about minus 5 it is all just 'Too Cold', I dont feel the difference much. But then I try to wrap up and keep moving or be inside! It's one of the reasons we built a mini barn, warmer for me to work in and also horses get the ambient temp inside the barn warmer than outside, even with their exterior windows open.
