#15-#16 a long pause to read the map on top of the first hill
#16-#17 a small correction to the south just before the control
#18 had a reasonable plan and executed it OK.
#19 again a long pause to read the map
#20 found the swamp instead of the lake 🙁 didn't have a good plan when leaving #19
#21 again poor planning running up/down hills instead of around them.
