I'm glad you liked the course. I also failed to notice the 1:7500 scale until towards the end of the day Saturday.
Yes, there were 3 pairs of controls that were visible from another control. I should have eliminated the 15th control completely, and moved the 19th control north east. (See
RouteGadget)
Actually, on #26, the optimum route was
supposed to be north on the flat route. But, when Pat Meehan + me + 3 other juniors did the red course together, Sam Gordon decided to take the lower route, and he beat the rest of us by over 30 seconds. I think he was slightly less tired than the rest of us though.
