Watch the part where Lloyd and Harry are at Aspen, and they are standing around the fire, then they start to fight. Watch during certain scenes when you can see the ground. You can clearly see that the snow is some type of cotton or something like that. Also when Lloyd and Harry are walking on the sidewalk with the briefcase, (talking about IOU'S and their word is their bond) one of them, as he steps up on the curb, actually flips up a piece of it with his foot.
