You left out my favorite navigational aid: a road sign with directions (or distance) to my destination. I've misread paper cue sheets and maps, and we could start another thread with goofy GPS directions (e.g., turn left. 50 feet later, turn right. Situation on the road: there's another road on the right, and nothing visible to the left). But when a sign points thataway to Tall Trees Campground, I've got a solid feeling Tall Trees Campground is thataway.
