I have been collecting old clothing to hopefully put into a 4'X4' Third Hand target sometime in the future. Has anyone put one of these together for outside use? Obviously I would want to keep the sun off of the skins, but I am wondering how it handles rain. I figure I need to put a small sloped roof above it at the very least, but it will be in the path of the sprinkler system. Do I also need to come up with some kind of cover for the face? The target would be backed up to the southwest corner of the fence, so will only have overhead, north, and west exposure.
