Ahh yes, the dark winters in Alaska! what part do you live in pat?
I agree with pat, you need to figure out how to do this, is it 15 min. sessions a few times a day on the treadmill? is it a walk to town? is it finding a buddy to join the gym. is it what you do when you allow yourself to watch TV.
I am not sure where you are in the "north" it is cold, but a warm coat, a hat and gloves, and comffy boots and you will be suprised at how warm you get walking outside, how much better you will feel getting out and that you can DO IT!
I must say, and Pat will agree that what gets me going in my ipod. I just got a waterproof case for it and waterproof headphones and I am about to start swimming with my buddy KFS who just had WLS. ( I hate swimmming in the winter, but that is waht friends are for

)
So my advice is keep coming, read post, ask questions and get going for you.
