The course measurement I did yesterday went well. But since it was in a state park, there were rarely permanent landmarks to reference my measured points against. Most of the time, I was on a road surrounded by nothing but forest. I measured points from permanent objects as much as possible, but they just weren't available for a couple of my points. Of course, everything's marked by P-K Nails (as well as paint), but will the lack of landmarks be a problem for those points?
