I know what you mean Dave, by the way when you start taking winter pictures onto the theme thread I'll have a head start
I'm waiting for a day above 15* with some sun and I'm going to go take some pictures. It's been really cold here as in kill your batteries cold. When times get tough I wrap the MD80 power grip with 4 of the dry chemical hand warmer packets so I can go for a day without the temperature sapping the power too much. I've ordered a new set of batteries because all that I have are about 4 years old. They don't hold charge like they used to and when it's below 0 they go quickly.
