Two mistakes, directly on #1 and then on #12. Ran past both of them and had to backtrack to find them..
Spent an unbelievable 17 minutes looking for nr3... Should have gone directly east from nr2, but somehow drifted too much south, and then ran around in circles for a while, actually using nr7 to put myself back on the map.
Not sure I agree 100% with the placement of nr5 (and thus the squiggle in the gps-trace), I feel it was in reality placed slightly differently compared to how it was drawn on the map.
Otherwise mostly OK.
