So I've started roaming, checking out some of the areas people have mentioned might be suitable.
I made it to the top NW corner, where HenriD had suggested first, bumping into invisible lines along the way and it's looking pretty good, it's much "wilder" than alot of the rest of the map, and the terrain under the tree canopy is full of interesting hills and holes and cliffs. There are also some patches of jungle here and there, and thats where my search ended, I'd made it to the top of a jungle tree, surveyed the area, fell off, lost my gear, didn't set a save point and wound up back at the hunger arena where I'd used the bed and forgot days before!... Then the server went down, and that was enough for the night for me
Be on to check out some other areas sarvo/tonight and hopefully try set a save-point in them for future
