| kupackman: | Word on the veggie boundaries. I don't like to rely on them as primary features, but sometimes, I had to, and it wasn't pretty. |

| TBorish: | When I first started orienteering, I tried to use vegetation boundaries and then I learned that contours are really the only feature you can consistently rely on. This course forced me to forget 3 years of advice on not using vegetation. |

| ebone: | Relying on contours primarily is the right thing to do >95% of the time, but this terrain/map/course combination had many parts in the other <5%. For me, the need to adapt my technique to novel conditions is what makes orienteering very interesting (and sometimes frustrating). The key to successfully adapting is to quickly figure out how the mapper represents the terrain and how the course setter places the controls. In this case, the vegetation (especially clearings) looked a lot more distinct on the map than it appeared in the terrain, and the controls were often placed very low behind small, hard-to-see point features. The result is that you had to know where you were by using compass and distance estimation from the distinct features (roads, distinct contour features), so that you could narrow down your location on the map to a small area in which you had to match the map to the terrain to pinpoint yourself, and subsequently, the control. |
