Last year my daughter’s class went ona field trip to a huge corn maze. I wentalong to help chaperone and was givenfive kids to watch. We set out withconfidence that we could find the exit.We got utterly lost. Fortunately, we metsome other groups that had cheatsheets. They had a map of the maze withlandmarks. With that, it was pretty easyto get out. It was if we had a view fromabove.
