BIG mistake while looking for 17. Must have spent a good 15 minutes in that wrong trail.
Other mistakes was on top of hill looking for 23, went along evergreen boundary on 21, overshoot stream going to 28 by 100 meters and had to return back on main trail to find stream (which, plus, was the wrong stream, parallel to the actual stream).
Between 20 and 40, after the powerline and once in the evergreen forest, picked up a faint trail that guided me almost to the control area.
Felt "remote" and "away from civilization" while bushwacking after 30 trying to reach trail to 10, and also between 40 and 39, and also between 38 and 19. Was happy to find trail after that.
Lost my control card near 24, punched the rest on the clue paper sheet. Control card was found by others and returned later.
