A nice signal flag is a good way to indicate where your camp is located, especially if that flag has a contrasting color and can be seen from a great distance. Make sure you secure the flag tightly to branches, poles, or objects that cannot fall down. Tie up bandannas, strips of non-essential clothing, reflective items you can spare--whatever sticks out against the landscape. And make it sturdy. During some training this past weekend, some of my students built a great looking survival shelter, and hung a very prominent red jacket on a tall pole. This looked great, until it fell over and couldn't be seen at all. Lesson learned. Let's hope none of us ever learn a lesson like that the hard way.
