hmmm, tricky, this post is going to make me late for work :)
My initial
route is shown here... but after looking at Ian's I think that it might make most sense to leave the control and go through the Northern tip of the wide field. Scrambling up the ridge to the right of the green patch might not be so bad...
I worked backward from the control deciding a) that I wanted to attack from above and that meant that I probably wanted to come through the parking lot by the pond. Then it was tricky to decide the best way to get there... the road is tempting but added some distance.
