You can do it like I did it. Go to #1. Then go to #5 and be excited thinking you've arrived at #2, then realize you're not where you think you are, but can recover, maybe. Head to #2, lose touch with map (not field checked here?), climb to highest point to relocate, finally find #2, then continue on as far as #15 and run out of time. I AM curious to know how long it would take to walk, accurately, the whole thing. Have fun.
