I guess I am replying to myself here. I have had a chance to use the REI 9x9 Camp Tarp on several trips and it worked out perfectly. We happened to have good weather, but I am certain it would have worked well in a rainstorm. I would bring three sides down to the ground if it were raining and windy. Perhaps even drop the top peak some, but there is plenty of room for two under the 9x9, three wouldn't even be a squeeze. It sets up quicker than any tent I have had. You put in three stakes and then lift the remaining corner and tie it to a tree (or trekking pole with guy). A little adjusting here and there and you are done in a few minutes. It is a little bigger and heavier than I need, but my pack is so light otherwise that I don't mind because of the extra space, and someday in an emergency I can share the space with someone.
