@jmarro,
The weather is worse than Minnesota even. In different ways. But I was colder during the London winter than I ever was in Minnesota. (The persistent dampness meant that I never seemed to be able to warm up all the way -- Minnesota cold is cold but dry and with enough down and wool you can warm up.)

P.S.: While the winter was seriously hard to deal with, the spring was glorious. The lush greens were gorgeous.
