Mostly a good run. Precise bearing and pace count got me in great shape thru the first 8 controls -- in 5th position overall on Green at that point, nailing all the flags. Read the features okay and picked off landmarks as I went by. All nicely done.
Then to 9 drifted R down a logging ride when I wanted to head due N across the marsh. No marsh, but "maybe it was dry". Decided I had drifted L and corrected E when the rides didn't match up. That put me way off the target, bordering on the OOB area. Next hour spent relocating and searching. Ultimately was able to nail down position from the ride junctions and some topography. Wow! That took me from 5th to 54th! Track shows I had gone R of the marsh instead of L .
A clue before that was a muffed pace count to 8, even tho I nailed the control. Should have taken that as a big warning my concentration was fading. After 43 min I needed a brain gu.
