Thought I would share this. I had a ball with my son yesterday in the foot of new snow we received. I don't know if we are making a wall or a whole fort yet, I guess I will see how it develops today. We just started packing snow in some bins and now we have snow blocks. He was having a ball. He has already started building a pile of snow balls for his ammunition against his sisters and has placed them behind the protection of the wall.
