This year, instead of buying a tree that's already chopped down, why not make an outing to a Christmas tree farm to cut down your own tree? Not only will you be supporting a local family-owned business, but you'll get some exercise hiking through the rows of trees to find the perfect one. Then once you find it, you'll burn some calories sawing it down by hand. Even if the whole process only takes 30 minutes, you'll still burn at least 100 calories. If you're not sure where to go in your area, check out this Christmas Tree Farm Directory. Happy decorating!
