We always carry emergency food no matter what time of the year it is.
Losing our footing on something is what I'm really concerned about. We're going to have to be a bit more careful for the first couple months. Between base layer bottoms, hiking pants, and water proof pant. That should keep us plenty warm and dry while we're hiking. We've got down/wool layers for at night for warmth. If that's not enough we'll get into our sleeping bags. If we're still cold after that we'll pitch the tent.
We've focused on the picture, and we know this isn't going to come easy. We're going to be cold, wet, and at each others throat sometimes. We'll also be there to motivate each other, and to push each other.
No matter how bad the day is, it's still better than working 9-5.
