MVOC Green course at Caesar Creek State Park - several inches of snow. Major 10 to 13 minute multiple errors on control 7. (This was all in a very flat, pretty much featureless area with a few ruined fences that should have been perfect catching features). I think I wasn't careful enough with compass, hit a fence that went at about 45 degree angle to the one I intended to follow, followed it the wrong way for a ways, realized the bearing was off and corrected. Hit another fence which the angle also appeared to be off, but was probably the correct one; thought I had relocated when I hit a minor path paralleling the fence, but turned out to be an unmapped path and ended up following it the wrong way and finally relocating on the reentrant system not far from control 8 (6-7-8 was a roughly 50-55 degree dogleg). For there it was easy to 7, then right back the same way to 8, then reverse the route again to get to 9 (since 7-8-9 was a roughly 30-35 degree dogleg).
Hamstring started to twinge just a little bit going up a steep hill to 13, so I was a little more cautious on the legs for the final few controls. Wasn't careful enough with navigation again going from 16 to 17, and while I intended to do a gentle "C" shape to get around big reentrants, I initially went too much north and not enough west and did more of an L... Probably cost another 2-3 minutes.
Otherwise, pretty clean navigation, just slowed by the deep snow.
