Remove the ladders from the raft and from the dock. Store them under the camp, on the ledge outside the bunk room.
Leave the Adirondack chairs on the deck and on the dock.
Collapse the umbrella above the outside dining table. (This should be done when the umbrella is dry. Since the weather is unpredictable, consider doing this one or two days before the date of your departure.) Lean it in the corner of the main room that is nearest to the outside dining table.
Collapse the outside dining table. Store it in the main room.
Collapse the outside dining chairs. Store them in the main room.
Roll the Big Green Egg into the main room.
Bring in the hammock. Hang it from a truss in the main room, using the two nails that are marked with trail ribbon.
