is hard. The visibility is low and the contour detail is very subtle, which makes it really difficult for beginners and, especially, intermediate orienteers. I think setting a good Orange course at Lynn Woods is pretty hard, unless you go for more trail route options and less woods navigation. Your race sounds fun though. Seems like a really good initiative!
"So, I did a little instruction, and we walked together to their #4 as I explained some tips and tricks (northlines FTW! and wow, turns out if you make a plan based on features in the map, you don't have to rely on a dead reckoning. Oh, and scale... it matters), and shadowed for a bit to make sure they got it. The kids were bright, attentive, and interested, and the grownup was also into it." -> I think this type of in-the-woods-instruction can actually be quite valuable. Obviously also takes a lot of people-power. But, I've used similar when teaching my friends and found it effective since you get to correct/respond to things as they are happening.
Yes, exactly - you can see what they do when you say "orient your map, and now face the direction you want to go", and each boy is facing a different direction...
Just wish I'd been able to do this earlier in their course.
