Discussion: mapping trails under overhanging rock structures?

thx, ndobbs. i have been schooled!

Twice before from memory.

But is it the same overhanging feature each time?

Probably. It's a pretty cool feature. ;-)

There was an overhanging hedge at the sprint event I went to on the weekend. I thought it was marked as grey but it turns out it was just white.
