I always practice picking routes on the blank maps then see how they compare to your routes (usually quite similar!).
BTW, what happened on #1 on the third course? Were the woods just too thick to enter?
They looked awful, but I think I was just being stubborn. I think it got better after the first 10 or so meters. I certainly went through a lot of what I would have mapped as dark green, and I was just getting tired of it. Pretty green the way I went, too, but at least I had a long road run to think about it.
