Woodworking 101

We have four really large willow oaks in the front yard which we love dearly (except in autumn). About a week ago, during a storm an almost thirty foot limb came down with a thud. I finally got it cut up this morning and put out on the curb before the yard waste crew got here. Unfortunately, all I have is a bow saw, so it took a while and my right arm now hangs down to my knees.
