While I don't usually like cold weather, it dropped below freezing here in Lethbridge last night too. It was really great for the weeding though - all my weeds just died overnight! Anna's next-door neighbour had a particularly bad dandelion problem - they had dandelions but no grass. Now they have a front yard full of dead dandelions. It almost looks like really well groomed grass through the morning mist. They must be especially happy.
