Some roads may be shown as easements, they may or may not exist. If they are gazetted and travel through private property, you may well use your right of way, but please ask permission, to stay in the good books. In old logging areas there may be quite a lot of old logging tracks, these may well be overgrown with regrowth. They normally lead to a log landing area, then out to an access road. Some old forestry maps show the major access tracks though these areas.
Pads are either man made or animal tracks.
It is surprising to see various pads in the remotest locations. Cattle and other animals tend to form pads between their grazing areas and their water supply. The goats and deer in Sundown Park form pads that, if your lucky, go in the general direction you wish to travel. It is a general rule that it is better to travel on ridges than valleys. There is a better chance that a pad will be found on top of a ridge and the vegetation less dense.
