Good advice ^^^but don’t get too caught up on south facing around PG because a lot of areas are too flat. In simpler terms look areas that see lots of exposure to the sun promoting growth. In areas with good elevation changes yes south facing slopes but in flatter areas it’s more so about how opening in the trees let in more sun, lake shore, river banks, old roads that get lots of light or landings. The basic idea is the same it’s all about sunshine
Willow river area east of PG is worth while
