Many paths near the Brda River are in the same condition, so it is not the reason to delete them from OSM. About path visibility. 1 year ago the path near Kartodrom was in the same condition (you can see it on the old mapillary record) but now it looks much better, do you know why? Because some volunteers care about it, made a cleanup on this path, and now it looks much better. You can also make a cleanup on this path near PZM for better visibility. This path near PZM near Brda River is the only legal option to go through because it's forbidden to go by PZM's tracks.
