When I pack up in the morning I frequently have to give the tent a good shake before I can pack it away. On the last trip of four days I had rain on two of the nights and on one other night the tent was frozen solid so shaking the tent is necessary. Even when I do not have rain the bottom of the tent is usually covered with dirt and/or leaves etc. Once I have shaken off the tent I do not really want to lay it down again in the wet and dirt. I do not want to carry dirt and water until the next night. That is why I put the tent over my shoulder while packing it.
